mb/google/volteer: Fix USB4 enabling for volteer family
volteer baseboard was currently enabling TBT(USB4) devices in
baseboard devicetree and also selecting the Kconfigs required for
resource allocation above 4G for the USB4 controllers. However, not
all volteer devices have USB4 support. This change fixes USB4 enabling
for volteer family by making the following udpates:
1. TBT devices are moved from baseboard devicetree to individual
override trees for the variants that actually support USB4.
2. When moving TBT devices to override tree, tbt_pcie_rp0 is marked as
on instead of hidden for all variants other than volteer
reference. This is because volteer reference is the only device that
has an asymmetric support for USB4 (i.e. does not support USB4 on C0
port).
3. Kconfig selection for PCIEXP_HOTPLUG is moved to Kconfig.name for
these variants.
