Subject: [PATCH net v3 3/7] net: dsa: mt7530: fix trapping frames on non-MT7621 SoC MT7530 switch

From: Arınç ÜNAL <arinc.unal@...nc9.com>

The check for setting the CPU_PORT bits must include the non-MT7621 SoC
MT7530 switch variants to trap frames. Expand the check to include them.

Fixes: b8f126a8d543 ("net-next: dsa: add dsa support for Mediatek MT7530 switch")
