Subject: [PATCH 2/2] platform/x86/intel/pmc: Remove unnecessary ioremap

pmc_get_pmc() unnecessarily calls ioremap to access memory that is already
available through a variable passed in as an argument. Replace the
redundant ioremap call with direct use of the provided variable, and remove
the ioremap and iounmap calls.
