it83xx: pull more functions into __ram_code section
Because we have space in the section, so we pulled more functions
into the section. If a function is cached in __ram_code section
(static cache), we can save latency of fetching code of the function
from flash. (Fetching 64 bytes code from flash takes about 4us latency)
BUG=none
BRANCH=none
TEST=buildall.
Asurada and Drawcia are both able to boot to kernel.
