Add HI3670 SoC UFS driver support by extending the common ufs-hisi
driver. One major difference between HI3660 ad HI3670 SoCs interms of UFS
is the PHY. HI3670 has a 10nm variant PHY and hence this parameter is used
to distinguish the configuration.

Hynix ufs has deviations on hi36xx platform which will result in ufs bursts
transfer failures.
To fix the problem, the Hynix device must set the register
VS_DebugSaveConfigTime to 0x10, which will set time reference for
SaveConfigTime is 250 ns. The time reference for SaveConfigTime is 40 ns by
default.
This patch is necessary to boot on HiKey960 boards that use Hynix UFS chips
(H28U62301AMR model: hB8aL1).
