Subject: [PATCH] phy: qcom: qmp-ufs: update SM8650 tables for Gear 4 & 5

Update the SM8650 UFS PHY init tables to support Gear 4 and Gear 5
using the overlays setup (only supported Gear 5 before), and sync
back with the latest Qualcomm recommended values.

The new recommended values allow a solid 50% bump in sequential
read/write benchmarks on the SM8650 QRD & HDK reference boards.

I'm gonna trust you on copypasting these numbers properly as I
have no sources.. but that 50% speedup does look very nice!
