[PATCH net-next 1/4] net: macb: Rename MACB_CAPS_QBV to MACB_CAPS_TC

[Vineeth Karumanchi <vineeth.karumanchi@amd.com>]

The MACB_CAPS_QBV capability flag was originally introduced to
gate TAPRIO/QBV support. However, GEM IP versions that support
QBV also implement multiple TSN clauses.

Replace this with a generic capability flag that can be reused
by other TSN features. Rename MACB_CAPS_QBV to MACB_CAPS_TC to
better reflect its role as a general traffic-class offload capability.

The supported TSN clauses are handled through macb_setup_tc().
