This patchset introduces ExynosAuto v920 SoC ufs phy driver as
Generic PHY driver framework.

Changes from v2:
- simplify function name from samsung_exynosautov920_ufs_phy_wait_cdr_lock
to exynosautov920_ufs_phy_wait_cdr_lock
- return immediately after getting the CDR lock
- add comment for wait CDR lock

Changes from v1:
- use exynosautov920 instead of exynosauto to specify
- remove obvious comment
- change soc name as ExynosAutov920 to keep consistent
- use macros instead of magic numbers
- specify function name
- add error handling for CDR lock failure
