ACPI: PMIC: allow drivers to provide a custom lpat_raw_to_temp() function 

The LPAT tables used in the DSDT for some PMICs require special handling,
allow the PMIC OpRegion drivers to provide an alternative implementation
by adding a lpat_raw_to_temp function pointer to struct pmic_table;
and initialize this to the default acpi_lpat_raw_to_temp function
for all PMICs.
