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.

Added initial support and created the corresponding device tree part for
building PSoC6 SoC as part of Zephyr.
