[U-Boot] removing bit reversing for SCFG in immap_ls102xa.h

[Sinan Akman <sinan@writeme.com>]

   Hi Alison

   I was just testing out ls1021atwr board with NOR
boot using rcw_1000.bin.

   I noticed that Ethernet is not working.

   In ls1021atwr.c we have :

   out_be32(&scfg->etsecdmamcr, SCFG_ETSECDMAMCR_LE_BD_FR);
   out_be32(&scfg->etsecmcr, SCFG_ETSECCMCR_GE2_CLK125);

   In your earlier commit c207ff612903389f8b32e377fe32be43e6efd8f7
you removed the bit reversing around this but those defines are not
in big-endian. By setting bit reversing before those lines as
before makes Ethernet working.

   Could you please take a look at this. Should we reverse
your commit since we are accessing SCFG registers directly
in the board specific files ?
