Andy Shevchenko 68872eb9b1 x86/platform/intel/pmc_atom: Export accessors to PMC registers ...

Export the pmc_atom_read() and pmc_atom_write() accessors to the PMC
registers. On early initcall stages the functions will return
-ENODEV, and caller has to wait when it will be available.

Additionally make absence of debugfs a non-fatal error.

The patch will be useful for the upcoming fixes regarding to the
LPSS block found on Intel BayTrail-T and Braswell.
