Refactor the pinctrl nodes slightly so that the port devices are not
child of the main pinctrl node. This is because the pinctrl node is
being used as parent for pinctrl setting nodes itself, and having the
port nodes as child end up creating a circular depdency with the edt
child enumeration patch.

In order to bring consistency in-tree, migrate all dts code to the new
prefix <zephyr/...>. Note that the conversion has been scripted, refer
to zephyrproject-rtos#45388 for more details.

Introduce a new "zephyr,memory-region" compatible to be used when a new
memory region must be created in the linker script from the devicetree
nodes using the compatible.
Remove also the LINKER_DT_REGION_FROM_NODE macro and add a new
LINKER_DT_REGIONS macro to cycle through all the compatible regions.
In the same PR modify the DTS files and the linker scripts.

The psoc6 SoC has 2 cores, each with different allowed priority ranges:
CM0: 0-3 (2 bits of NVIC prio, no prio reserved by the kernel)
CM4: 0-6 (3 bits of NVIC prio, one level reserved by the kernel)
Since some of the peripherals are only available to the CM4, those
should be set to a priority that is actually valid for it. In this case
the lowest possible one is 6, so transition from 7 to 6.

The current serial driver uses hard code configuration. Rework driver
to use pinctrl and enable full configuration from device tree.

Introduce PSoC-6 pinctrl infraestructure and definitions. This add
files to handle devicetree entries and following modifications:
- add pinctrl bindings
- update gpio bindings with pin-cells
- add pinctrl node and move gpio nodes inside
- declare pinctrl for current uart entries

PSoC-6 SoC needs that user define the nvic interrupt number to bind
with the peripheral interrupt line for the Cortex-M0+ CPU. It uses
a multiplex before any NVIC interrupt line. The interrupt vector is
selected using interrupt-parent property with the intmux_chN number
reference.
Note: The PSoC-6 SoC allows that both CPUs receive the same interrupt.
A tipical use is GPIO interrupt handle and user is responsable to
define interrupt line, priority and take care of enable same peripheral
instance on both CPUs only when appropriated.

The psoc6.dtsi file declare a reference to nvic. Since it was proper
defined at psoc6_cm0/4.dtsi files this entry is redundant. Drop the
useless entry.

The true mmio-sram nodes should not have had a 'device_type' property.
Remove it from the cases that we clearly know are SRAM.
