i2c: Move I2C_MAX_HOST_PACKET_SIZE to i2c.h
This patch moves I2C_MAX_HOST_PACKET_SIZE to include/i2c.h. It's currently
used only by i2c-stm32*.c but should be commonly available for other chips.
It also moves i2c_get_protocol_info to common/i2c.c for the same reason.
BUG=none
BRANCH=none
TEST=make runtest
