Many vendors would like to disable host TX LCC during initialization
flow. Introduce a common function for all users to make drivers easier to
read and maintained. This patch does not change any functionality.

This patch disables autohibern8 feature in Cadence UFS. The autohibern8
feature has issues due to which unexpected interrupt trigger is happening.
After the interrupt issue is sorted out, autohibern8 feature will be
re-enabled

Some UFS devices have issues if LCC is enabled. So we are setting
PA_LOCAL_TX_LCC_Enable to 0 before link startup which will make sure that
both host and device TX LCC are disabled once link startup is completed.

Configure CDNS_UFS_REG_HCLKDIV in .hce_enable_notify() instead of
.setup_clock() because if UFSHCD resets the controller ip because of phy or
device related errors then CDNS_UFS_REG_HCLKDIV is reset to default value
and .setup_clock() is not called later in the sequence whereas
.hce_enable_notify will be called everytime controller is reenabled.
