Rename is_primary to is_secondary. The justification for this is
because it is less likely to have something configured to be
secondary, and the 0 value would be if it is primary.

Previously, a call to set the net_context state was added here to
accommodate a new KConfig scenario that permitted disabling offload
sockets. This code path is used by both local and offloaded sockets.
While it is necessary to update the state of the net_context for a
locally managed socket, setting the net_context for an offloaded socket
is an error, as the net_context is invalid (in fact, it points to a
hard-coded dummy socket), as observed in #52346 and #38544.
A prior commit (a9ac0a88) attempting to remedy the offload socket
scenario removed this line, which resulted in problems for the local
socket scenario. The socket never got updated to the connected state,
and thus was unusable.
Adding this guard allows the eswifi socket to set the socket net_context
only if the socket is NOT offloaded.

In Infineon XMC4XXX SoCs, gpio interrupts are triggered via an
Event Request Unit (ERU) module. A subset of the gpios are
connected to the ERU. The ERU monitors edge triggers and creates
a SR.
This driver configures the ERU for a target port/pin combination
for rising/falling edge events. Note that the ERU module does
not generate SR based on the gpio level. Internally the ERU
tracks the *status* of an event. The status is set on a positive
edge and unset on a negative edge (or vice-versa depending on
the configuration). The value of the status is used to implement
a level triggered interrupt; The ISR checks the status flag and
calls the callback function if the status is set.
The ERU configurations for supported port/pin combinations are
stored in a devicetree file dts/arm/infineon/xmc4xxx_x_x-intc.dtsi.
The configurations are stored in the opaque array
uint16 port_line_mapping[].

Change Summary:
Update Base addr to set direction to use Aligned IP base address instead
of Port Base Address. Port Base Address + offset to direction register
will set incorrect value for Port B,C & D. For ex: In cases when more than
1 port is configured on the same IP, the DTS node for port B will start
at offset 0xC. Calculating the port using Port Base will yield offset of
PORTB DIR register which is at offset 0x10 from Aligned Base, and as a
result will result in setting DIR register of PORTC instead.

For architectures that rely on a PCIe controller (for example, ARM64),
scanning the PCI space will only succeed after the controller has
initialized. Therefore, in the presence of PCIe controller, the PCIe
initialization is bumped to the next system init level.
In the past, drivers like ivshmem would do a late scan of the PCI space
in case the early scan failed; however, the cited commit removed this
feature and ivshmem fails for ARM64. This commit fix this by making the
early scan succeed.

This function is responsible for checking if combination of msize,
mburst and FIFO level is allowed. Possible combinations can be found in
ST documentation, eg. Table 36. FIFO threshold configurations, RM0402
9.3.13 FIFO chapter.
Previously there was no 'break' or '__fallthrough' in msize switch which
caused compilation errors. Since we are confirming that combination is
correct, 'break' statements should be used.
Besides of introducing missing 'break' statements, this patch moves
'return false' from switch to the end of the function. This makes code
shorter and easier to understand, because we have only correct
combinations.

STM32 counter driver uses switch statement in which cases don't end
with break or return intentionally.
Affected switches in counter driver check status of all timer channels
(maximum 4 channels), but the number of channels is not determined
during compilation. In switch, we jump to channel with highest number
and then check other channels with lower numbers.

- Similar to what was done for other parts of the driver, remove any
register specification from Devicetree (modesel-reg/mask)
- Keep all the information in the driver, and define modes as "numbers",
e.g. PCA9420_MODE0: 0, PCA9420_MODE1: 1, etc.
- Bindings provide IC defaults now (all modes allowed 0/1/2/3 and
initial mode set to 0).
- When mode is controlled via the MODESEL0/1 pins (ie directly by an iMX
MCU using the dedicated PMIC_MODE0/1 pins), the driver will not allow
to select a mode (it is not possible). This mode is now enabled by
setting `nxp,enable-modesel-pins` in Devicetree. When enabled, all the
allowed modes are configured to be selectable via pins. When disabled,
mode can be set via I2C (using TOP_CNTL3 MODE0/1_I2C fields)
