max32660: add I2C board support for stand-alone read transactions
Adds support for solitary I2C board read transactions that are not
preceded with an I2C write.
BRANCH=none
BUG=none
TEST=Slave tested with EC CMDs and board cmds sent from a custom written
EC HOST using another MAX32660 device as an I2C Master. Tested with
Raspberry PI that emulates EC HOST and board commands.
