ls102xa: etsec: Use proper settings for BE BDs
Replace the DMACTRL[LE] hack with recommended settings
for ETSECDMAMCR to get the same end effect - obtaining
big-endian buffer descriptors and frame data for eTSEC.
The reset / default value for ETSECDMAMCR is preserved,
excepting the BD and FR bits which are cleared to enable
the BE mode in accordance with the H/W specifications.
Fixes: 52d00a8 "ls102xa: etsec: Add etsec support for LS102xA"
