usb_mux: Add driver interface for USB-C muxes
In preparation for adding support for additional USB-C mux chips, add a
new high-level USB-C mux interface usb_mux.c. usb_mux functions are now
called from pd code instead of board-level functions. usb_mux calls down
into a mux chip-specific driver (currently pi3usb30532) or
board-specific drivers which toggle GPIOs (for legacy boards).
BUG=chrome-os-partner:41696
TEST=Manual on Glados in subsequent commit. Verify set() and get()
functions set and return consistent values. Verify that USB SS device
functions when muxes are set to dock or USB. Also, verify that DP
dongle and USB SS device are functional on both PD ports on samus_pd.
BRANCH=None
