Platform specific initialization during early boot
has been a feature supported only by Cortex-M; the
Kconfig symbol is defined in arch/arm Kconfig space.
We rename the z_platform_init() function to
z_arm_platform_init(), to indicate more clearly that
this is an internal, private ARM-only API.
This commit does not introduce behavioral changes.

Add infineon XMC4 series UART support. Driver supports
only poll mode using XMCLib.
Out of 4 available UART's on SoC, only UART1 is confgired
by default in UART mode until GPIO & pinctrl support.

Add infineon xmc series with XMC4500 support. XMC series comes with,
- CPU operates upto 120MHz
- 3 RAM (PSRAM1 - code, DSRAM1 - data and DSRAM2 - communiation)
- upto 1MB flash
init: clock control & gpio is not done, so SoC initialization directly
relies on HAL. Core operating clock is stored in no_init section, which
is kept under DSRAM1. Only DSRAM1 is used until clock support. Using
PSRAM1 and DSRAM1 needs adaptation in linker script - planned for next
revision.
Note: SystemInit cannot be consumed directly due to vector table +
HAL linker dependency.
