The SAM V71 SoC configuration currently selects the `ARM_MPU` symbol
and this effectively forces MPU usage on the SoC.
This commit removes `ARM_MPU` selection from the SoC Kconfig since it
is intended to be selected by a board, and the `CPU_HAS_ARM_MPU` symbol
already indicates that the SoC supports ARM MPU.

Reworked usart_sam driver to utilize new DT_INST macros as part of
this rework we also now get pin ctrl/mux configuration information
from the device tree instead of via Kconfig and defines in soc_pinmap.h
We remove defines from dts_fixup.h and soc_pinmap.h and associated
Kconfig symbols that are no longer needed due to getting all that
information from devicetree.
