can: rcar_canfd: Fix R-Car V3U GAFLCFG field accesses

Browse source

[ Upstream commit 9be8c55835 ]

Each Global Acceptance Filter List Configuration Register (GAFLCFG)
contains two fields, and stores the number of channel rules for one
channel pair.

As R-Car V3U and later can have more than 2 channels, the field
selection should be based on the LSB (even or odd) of the channel
number, instead of on the full channel number.
