phy: qcom-qmp-pcie: split register tables into common and extra parts

SM8250 configuration tables are split into two parts: the common one and
the PHY-specific tables. Make this split more formal. Rather than having
a blind renamed copy of all QMP table fields, add separate struct
qmp_phy_cfg_tables and add two instances of this structure to the struct
qmp_phy_cfg. Later on this will be used to support different PHY modes
(RC vs EP).
