Subject: [PATCH V4 07/11] phy: qcom-qmp-ufs: Remove qmp_ufs_exit() and Inline qmp_ufs_com_exit()

qmp_ufs_exit() is a wrapper function. It only calls qmp_ufs_com_exit().
Remove it to simplify the ufs phy driver.

Additonally partial Inline(dropping the reset assert) qmp_ufs_com_exit
into qmp_ufs_power_off function to avoid unnecessary function call.
