The UFS PHY found on SM6115/4250 is named v3-660, found on cheaper qcom devices
(possibly starting with sdm660), but up until recently wasn't used much due to
prevalence of sdhc port for internal storage/sdcard.

The name is a bit misleading, because most of the registers found on v3-660
don't share much in common with v3.

The register values/sequences are taken from OnePlus repo [1].

v1: https://lkml.org/lkml/2021/8/5/235

Changes from v1:
- Suggested by Vinod
  - removed v3-660 constants for regs with same name and value as v3 regs
