Volteer: Add support for RT1715
Add support for replacing the TUSB422 with the RT1715. Since they are
pin-to-pin compatible and currently only used with a rework, make the
decision of which to use at runtime. The logic is to check if the RT1715
is both on the I2C bus and the vendor ID matches. If either fail, default
to the TUSB422 address and driver.
BUG=b:162617664
TEST=make buildall
TEST=check both TUSB422 functionality and RT1715 functionality
BRANCH=none
