mb/google/brya: Fix pmc_mux port mapping for mithrax and felwinter

Fixes a pmc_mux port mapping error introduced in coreboot
commit 4fa8354

Mithrax and felwinter do not have sequential mux_conn[X] to connY
mappings which led to the kernel subsystem linking between Type C
connectors and USB muxes to be incorrect. The previous patch
attempted to fix this by changing the custom_pld layout. However
this broke USB 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.

TEST=emerge-${BOARD} coreboot
TEST=Manually check that usb-role-switches are mapped to the correct
    port.
  Attach USB 3 A to C cable from development machine to left port of
    DUT.
  Attach nothing to right-hand port.
  ectool commands below are only for felwinter as a workaround for
    devices without a firmware patch to connect superspeed lines.
  ectool usbpd 0 none
  ectool usbpd 0 usb
  ectool usbpd 1 none
  ectool usbpd 1 usb
  echo host > /sys/class/typec/port0/usb-role-switch/role (should
    succeed)
  ls -l /sys/class/typec/port0/usb-role-switch (note CONX-role-switch)
  echo host > /sys/class/usb_role/CONX-role-switch/role (should succeed)
  echo host > /sys/class/typec/port1/usb-role-switch/role (should fail
    as no cable attached)
  ls -l /sys/class/typec/port1/usb-role-switch (note CONY-role-switch)
  echo host > /sys/class/usb_role/CONY-role-switch/role (should fail
    as no cable attached)
