mtd: fix Orion NAND driver compilation with ARM OABI

We must tell GCC to use even register for variable passed to ldrd
instruction.  Without this patch GCC 4.2.1 puts this variable to r2/r3 on
EABI and r3/r4 on OABI, so force it to r2/r3.  This does not change
anything when EABI and OABI compilation works OK.

Without this patch and with OABI I get:

    CC      drivers/mtd/nand/orion_nand.o
  /tmp/ccMkwOCs.s: Assembler messages:
  /tmp/ccMkwOCs.s:63: Error: first destination register must be even -- `ldrd r3,[ip]'
  make[5]: *** [drivers/mtd/nand/orion_nand.o] Error 1
