scsi: ufs: renesas: Replace init data by init code

Since initialization of the UFS controller on R-Car S4-8 ES1.0 requires
only static values, the driver uses initialization data stored in the const
ufs_param[] array.  However, other UFS controller variants (R-Car S4-8
ES1.2) require dynamic values, like those obtained from E-FUSE.  Refactor
the initialization code to prepare for this.

This also reduces kernel size by almost 30 KiB.
