[PATCH v15 06/24] board: renesas: gen5-cm33: #undef field_{get, prep}() before definition

[Mikhail Kshevetskiy]

Prepare for the advent of globally available common field_get() and
field_prep() macros by undefining the symbols before defining local
variants.  This prevents redefinition warnings from the C preprocessor
when introducing the common macros later.
