[v3,0/2] Add UFS PHY support for SM6115/4250

The UFS PHY found on SM6115/4250 has a lot of common registers with ufs phy v2,
even though in downstream it is named v3-660. Due to register similarity with
v2, the few extra registers that are needed are added as v2 registers.

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

v1: https://lkml.org/lkml/2021/8/5/235
v2: https://lkml.org/lkml/2021/8/13/889

Changes from v2:
- Suggested by Vinod
  - the 6115 registers had a lot in common with v2 registers (and not v3, as
    was initially assumed), so those were reused whenever possible, and new
    regs were added along other v2 registers.

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