Subject: [PATCH net] net: ti: icssg-prueth: Fix r30 CMDs bitmasks

The bitmask for EMAC_PORT_DISABLE and EMAC_PORT_FORWARD has been changed
in the latest ICSSG firmware.

The current bitmasks are wrong and as a result EMAC_PORT_DISABLE and
EMAC_PORT_FORWARD commands do not work.
Update r30 commands to use the same bitmask as used by the latest ICSSG
firmware.

Fixes: e9b4ece7d74b ("net: ti: icssg-prueth: Add Firmware config and classification APIs.")
