This converts the compile time option of
CONFIG_USB_PD_TCPM_TCPCI_MUX_ONLY into a runtime option to better
support draggon egg designs and reduce CONFIG complexity in general.
Introduce new mux_read/write to read from tcpc_config_t or mux driver
depending on new flag setting.
Audited all mux drivers for any use of tcpc_read/write and updated to
mux_read/write.

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.
