FROMLIST: scsi: ufs: core: Increase the UIC command timeout further

Browse Source 
On my development board I observed that it can take a little longer than
two seconds before UIC completions are processed if the UART is enabled.
Hence this patch that increases the UIC command timeout upper limit
further.
