media: rcar-csi2: Optimize the selection PHTW register
commit 549cc89cd09a85aaa16dc07ef3db811d5cf9bcb1 upstream.
PHTW register is selected based on default bit rate from Table[1].
for the bit rates less than or equal to 250. Currently first
value of default bit rate which is greater than or equal to
the caculated mbps is selected. This selection can be further
improved by selecting the default bit rate which is nearest to
the calculated value.
