Pull device descriptor reading out of ufs quirk so it can be used also for other purposes. Revamp the fixup setup: 1. Rename ufs_device_info to ufs_dev_desc as very similar name ufs_dev_info is already in use. 2. Make the handlers static as they are not used out of the ufshdc.c file.

Currently the all the slot processing for the completion queue is done in ISR context.

Immediately after successful UFS link startup, UFS link power mode would be in PWM-G1, 1-lane, SLOW-AUTO mode. But currently we are doing few of the DME local/peer attributes access before setting the "hba->pwr_info" to default power mode. If we are doing link startup as part of error recovery then old power mode might be set to FAST mode and doing DME peer access (after link startup but before updating "hba->pwr_info" to default power mode) unintentionally tries to switch from FAST to FAST_AUTO mode (if UFSHCD_QUIRK_DME_PEER_ACCESS_AUTO_MODE quirk is enabled). Above issue is fixed by setting the default power mode immediately after successful link startup.

UFS device requires to perform bkops (back ground operations) periodically but host can control (via auto-bkops parameter of device) when device can perform bkops based on its performance requirements. In general, host would like to enable the device's auto-bkops only when it's not doing any regular data transfer but sometimes device may not behave properly if host keeps the auto-bkops disabled. This change adds the capability to let the device auto-bkops always enabled except suspend.
