[PATCH v6 07/26] pinctrl: ma35: #undef field_{get,prep}() before local 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.
