Commit Message

Yoshihiro Shimoda July 9, 2024, 2:35 a.m. UTC 
Since the current UFS controller of R-Car S4-8 ES 1.0 only requires
statical values for initializing it, the driver has const ufs_param[]
array. However, other UFS controller (R-Car S4-8 ES 1.2) will require
dynamic values like eFuse values. So, refactor initializing code for it.
