Subject: [PATCH v2 14/17] scsi: ufs: qcom: Simplify ufs_qcom_{assert/deassert}_reset

In both the functions, UFS_PHY_SOFT_RESET contains the mask of the reset
bit. So this can be passed directly as the value to be written for
asserting the reset. For deasserting, 0 can be passed.

This gets rid of the FIELD_PREP() inside these functions and also
UFS_PHY_RESET_{ENABLE/DISABLE} definitions.
