Executing code out of RAM on IT8xxx2 requires that the relevant
addresses be mapped onto the CPU's instruction memory bus, referred to
by ITE documentation as Instruction Local Memory (ILM). ILM mappings
configure blocks of RAM to be used for accesses to chosen addresses when
performing instruction fetch, instead of the memory that would normally
be accessed at that address.
ILM must be used for some chip features (particularly Flash
self-programming, to execute from RAM while writing to Flash), and has
historically been configured in the Flash driver. The RAM for that was
hard-coded as a single 4k block in the linker script. Configuring ILM
in the flash driver is confusing because it is used by other SoC code as
well, currently in code that cannot depend on the Flash being functional
or in hand-selected functions that seem performance-critical.
This change moves ILM configuration to a new driver and dynamically
allocates RAM to ILM in the linker script, allowing software use of the
entire 64k RAM depending on configuration. This makes ILM configuration
more discoverable and makes it much easier to correctly support the
CODE_DATA_RELOCATION feature on this SoC.

This patch adds a clock control driver for GD32 platforms. It is
important to note that the driver is only able to handle peripheral
clocks, but not "system clocks" (e.g. PLL settings, SYS_CK, etc.). On
some similar platforms (STM32) this task is embedded in the same clock
driver, performed at init time but with no options to do any
manipulation at runtime via the API calls. The clock control API as-is
is really orthogonal to "system clocks", and it is arguably a bad idea
to embed system clock init code in a clock control driver. It can be
done at SoC level still using Devicetree as a source of hardware
description/initial configuration.

The I2C master supports two 32-bytes FIFOs, channel A and C
are supported now.
I2C FIFO mode of it8xxx2 can support I2C APIs including:
i2c_write(), i2c_read(), i2c_burst_read.
Test:
1. tests\drivers\i2c\i2c_api --> pass
2. Reading 16 bytes of data through i2c_burst_read() can reduce
0.52ms(2.4ms->1.88ms) compared to the original pio mode when the

This mirrors #36499 and other PRs that added them for other

This silences a large number of dtc warnings due to the missing
property. It seems reasonable to require an address-cells property since
any interrupt controller could be the parent of an interrupt-map.
The only device actually using interrupt-maps is neorv32, and it needs
an address-cells of 2 (since this is the default if none is specified it
worked like that before this change).
While I touched this, I reordered the properties for consistency across

The ns16550 flags reg-shift property as optional. In case it is not
supplied, the ns16550 driver relies on a value defined in <soc.h>, or,
by default it takes 4 (shift by 2).
This patch adds the property to all ns16550 nodes, with the following
values:
- 2 if SoC did not have any custom value defined by
UART_REG_ADDR_INTERVAL (corresponds to 1 << 2 = 4)
- If SoC defined DEFAULT_REG_INTERVAL (snps_arc_iot/it8xxx2), use such
value (4=2, 2=1, 1=0).

Changes signature so it takes uint32_t instead of pointer to a
register.
Later `sys_read*` and `sys_write*` functions are used, which cast
given address to volatile pointer anyway.
This required changing types of some fields in LiteX GPIO driver and
removal of two casts in clock control driver.
There was a weird assert from LiteX GPIO driver, which checked whether
size of first register in dts was a multiple of 4.
It didn't make much sense, so I removed it.
Previous dts was describing size of a register in terms of subregisters
used. New one uses size of register, so right now it is almost always
4 bytes.
Most drivers don't read register size from dts anyway, so only changes
had to be made in GPIO and clock control drivers.
Both use `litex_read` and `litex_write` to operate on `n`bytes.
Now GPIO driver calculates this `n` value in compile time from given
number of pins and stores it in `reg_size` field of config struct like
before.
Registe sizes in clock control driver are hardcoded, because they are
tied to LiteX wrapper anyway.
This makes it possible to have code, independent of CSR data width.
