t210: Correct device MMIO range
Address region from 0x0 to 0x00ffffff is used for IROM_LOVEC and
can not be accessed by Bootloader.
Issue found in CL: 283104 is captured by this patch.
BUG=None
BRANCH=None
TEST=Compiles successfully and reboot test does not crash in firmware
Here are memory mapping table before and after this CL for evt2 board:
