arm: omap: cm_t35: Remove CONFIG_SYS_BOOTMAPSZ to fix FDT Linux booting

With CONFIG_SYS_BOOTMAPSZ defined, recent Linux kernel booting
results in this error:

   Booting using the fdt blob at 0x81f00000
   Loading Kernel Image ... OK
ERROR: Failed to allocate 0x1189d bytes below 0x80004000.
device tree - allocation error
FDT creation failed! hanging...### ERROR ### Please RESET the board ###

Removing this define solves this issue.
