[ Upstream commit 2c606d138518cc69f09c35929abc414a99e3a28f ]
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.
