scsi: ufs-debugfs: fix reading the M-PHY RX attributes
DME attributes read/write commands need GenSelectorIndex argument and
according to UFS host controller specification, it should specify the
targeted M-PHY data lane.
This is the valid range of GenSelectorIndex for M-PHY attributes:
0 to (2 * PA_MaxDataLanes - 1)
Example (Note: PA_MaxDataLanes is UniPro protocol constant set to 4):
-----------------------------------------
MPHY Access target | GenSelectorIndex
-----------------------------------------
TX Lane0 | 0
TX Lane1 | 1
RX Lane0 | 4
RX Lane1 | 5
-----------------------------------------
This change makes sure that correct GenSelectorIndex is passed for M-PHY
attributes while it reading via debugfs.
