phy: qcom-qmp-ufs: Add support for configuring PHY in HS G4 mode

Add separate tables_hs_g4 instance to allow the PHY driver to configure the
PHY in HS G4 mode. The individual SoC configs need to supply the Rx, Tx and
PCS register setting in tables_hs_g4 and the UFS driver can request the
Hs G4 mode by calling phy_set_mode_ext() with submode set to UFS_HS_G4.
