net: dsa: mt7530: fix port mirroring for MT7988 SoC switch

Browse source

[ Upstream commit 2c606d1385 ]

The "MT7988A Wi-Fi 7 Generation Router Platform: Datasheet (Open Version)
v0.1" document shows bits 16 to 18 as the MIRROR_PORT field of the CPU
forward control register. Currently, the MT7530 DSA subdriver configures
bits 0 to 2 of the CPU forward control register which breaks the port
mirroring feature for the MT7988 SoC switch.

Fix this by using the MT7531_MIRROR_PORT_GET() and MT7531_MIRROR_PORT_SET()
macros which utilise the correct bits.
