[PATCH v2 3/3] clk: microchip: core: allow driver to be compiled with COMPILE_TEST

[Brian Masney <bmasney@redhat.com>]

This driver currently only supports builds against a PIC32 target. To
avoid future breakage in the future, let's update the Kconfig and the
driver so that it can be built with CONFIG_COMPILE_TEST enabled.
