mb/google/brya: Fix pmc_mux port in ec/google/chromeec for mithrax and felwinter
Fixes a pmc_mux port mapping error introduced in corbeoot commit I349682a6fe3fe4848e4e86d9c446530a31b35875.
Mithrax and felwinter do not have have sequential mux_conn[X] to connY mappings which led to the kernel subsystem linking between Type C connector and USB mux to be. The previous patch attempted to fix this by changing the custom_pld layout. However this caused USB disk access to break and to disable USB port usage except for charging.
This patch reverts the custom_pld layout and instead changes the pmc hidden and tcss_xhci port mappings to match the hardware layout.
