[PATCH v2 0/1] Allow platform drivers to update UIC command timeout

["Bao D. Nguyen" <quic_nguyenb@quicinc.com>]

The UIC command timeout default value remains as 500ms.

Allow platform drivers to change the UIC command timeout as they wish.
During product development where a lot of debug logging/printing can
occur, the uart may print from different modules with interrupt disabled
for more than 500ms, causing interrupt starvation and UIC command timeout
as a result. The UIC command timeout may eventually cause a watchdog
timeout unnecessarily. With this change, the platform drivers can set a
different UIC command timeout as desired. The supported values range
from 500ms to 2 seconds.

v1 -> v2: - Created kernel module parameter namely uic_cmd_timeout
            as recommended by Bart. Addressed some other comments.
          - Un-do the change in the include/ufs/ufshcd.h file
            which added the uic_cmd_timeout field to the hba struct.
	  - Removed the patch 2 in the series where the UIC command
	    timeout value was overridden by the platform driver.
