mb/google/brox/var/brox: Remove mux references from typec port

The Type-C kernel driver no longer programs the AP mux, as of
https://review.coreboot.org/c/coreboot/+/82077. So remove device
references to the TCSS Mux control device from the Type-C port driver.

This eliminates the following kernel error which was observed as a
result of the kernel trying to program muxes it no longer has control
over:

[    4.618600] cros-ec-typec GOOG0014:00: Failed to get mux info for port: 0, err = -95
[    4.618608] cros-ec-typec GOOG0014:00: Configure muxes failed, err = -95

BUG=b:341331428
TEST=Run system reboot; configure mux kernel errors no longer seen.
