soc/apollolake: Expose a function to read pmc bar

This patch exposes a function to read pmc bar.
    PMC bar is read in function read_pmc_mmio_bar which
    is defined static in file pmutil.c. This patch exposes
    that functionality to call it from other files.

BUG=chrome-os-partner:53438
    TEST= Read the PMC bar value properly from outside
          pmutil file.
