power: domain: renesas-r8a78000: #undef field_{get, prep}() before definition

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.
