Use devm_platform_ioremap_resource() to simplify the code a bit.

ufshcd_get_pwr_dev_param function and ufs_dev_params struct have been
relocated to ufs core. Switch ufs-hisi to the common interface.

devm_reset_control_get could fail, so the fix checks its return value and
passes the error code upstream in case it fails.

Without CONFIG_OF, the of_match_node() helper does not evaluate its
argument, and the compiler warns about the unused variable:
drivers/scsi/ufs/ufs-hisi.c: In function 'ufs_hisi_probe':
drivers/scsi/ufs/ufs-hisi.c:673:17: error: unused variable 'dev' [-Werror=unused-variable]
Rework this code to pass the data directly, and while we're at it,
correctly handle the const pointers.

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).
