arm: omap: cm_t35: Fix: Re-add GPMC_NAND_ECC_LP_x8_LAYOUT

Patch a7e36fc9 (mtd: nand: omap: remove unused #defines from common
omap_gpmc.h) removed some MTD related defines. Including
GPMC_NAND_ECC_LP_x8_LAYOUT. But this define is also needed for the
memory controller configuration (only the x8 defines are needed,
the x16 defines are the default). Without it the NAND subsystem is
not configured correctly and booting into U-Boot does not work.
