[RFC PATCH] UFS: Remove the timeout while send command

[Venkatesh Yadav Abbarapu]

Based on the UFS speed mode(HS or PWM) the timeout might vary and
can result timeouts.

ufs-versal2-pltfm ufs at f10b0000: Timedout waiting for UTP response
ufs-versal2-pltfm ufs at f10b0000: OCS error from controller = f
 
It's a temporary workaround to solve the timeout issue.
