mfd: intel_soc_pmic: Differentiate between Bay and Cherry Trail CRC variants
Both Bay and Cherry Trail devices may be used together with a Crystal Cove PMIC. Each platform has its own variant of the PMIC, which both use the same ACPI HID, but they are not 100% compatible. This commits makes the intel_soc_pmic_core code check the _HRV of the ACPI-firmware-node and selects intel_soc_pmic_config_byt_crc resp. intel_soc_pmic_config_cht_crc based on this. This fixes the Bay Trail specific ACPI OpRegion code causing problems on Cherry Trail devices. Specifically this was causing the external microsd slot on a Dell Venue 8 5855 (Cherry Trail version) to not work and the eMMC to become unreliable and throw lots of errors.
