Changes in v2:
 - Added items/description to reg in binding
 - Added missing pm_runtime.h inclusion
 - Moved pm_runtime_enable call to before registering PHY
 - Fixed pmos/nmos variable size for 5 bits calibration values
 - Fixed calibration for single-lane PCIe, as in, the ln1 rswn
   calibration nvmem value is ignored in code if it's single
   lane and will not return an error; this is due to the fact
   that, effectively, single-lane may have a zero calibration
   in tx-ln1-rswn which is fine, as that'd be anyway unused
 - Changed calibration data errors to dev_err_probe and changed
   the "no calibration for ..." message to dev_info instead

This adds a driver for the PCI-Express Gen4 "S-PHY" found in the
Genio MT8894, Kompanio MT8196, Dimensity MT6991 SoCs (which are
all variants of the same chip).

This was successfully tested on MT8894 and MT8196.
