drivers: serial: uart_sam: rework device tree support

Browse source 
Reworked uart_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.
