it83xx: disable ROM codestabilize-10866.B
We dont need to use ROM code in the codebase. DX with 512KB flash
space has an overlapping issue with the ROM code (0x70000 ~ 0x7ffff).
This patch is to disable ROM code so we can properly use
the 512KB flash space.
BUG=none
BRANCH=none
TEST=Run console command "md .b 0x70000 256" on 512KB part,
and the result is from flash instead of ROM code.
