fs_enet: fix freescale FCC ethernet dp buffer alignment
Clive Stubbings [Thu, 16 Jun 2011 22:30:39 +0000 (22:30 +0000)]
The RIPTR and TIPTR  (receive/transmit internal temporary data pointer),
used by microcode as a temporary buffer for data, must be 32-byte aligned
according to the RM for MPC8247.

Tested on mgcoge.
