phy: qcom: qmp-ufs: Fix SM8650 PCS table for Gear 4
commit 81af9e40e2e4e1aa95f09fb34811760be6742c58 upstream. According to internal documentation, on SM8650, when the PHY is configured in Gear 4, the QPHY_V6_PCS_UFS_PLL_CNTL register needs to have the same value as for Gear 5. At the moment, there is no board that comes with a UFS 3.x device, so this issue doesn't show up, but with the new Eliza SoC, which uses the same init sequence as SM8650, on the MTP board, the link startup fails with the current Gear 4 PCS table. So fix that by moving the entry into the PCS generic table instead, while keeping the value from Gear 5 configuration.
