[PATCH v6 08/26] soc: renesas: rz-sysc: #undef field_get() before local definition

Prepare for the advent of a globally available common field_get() macro
by undefining the symbol before defining a local variant. This prevents
redefinition warnings from the C preprocessor when introducing the common
macro later.
