net: dsa: mt7530: set all CPU ports in MT7531_CPU_PMAP
MT7531_CPU_PMAP represents the destination port mask for trapped-to-CPU frames (further restricted by PCR_MATRIX). Currently the driver sets the first CPU port as the single port in this bit mask, which works fine regardless of whether the device tree defines port 5, 6 or 5+6 as CPU ports. This is because the logic coincides with DSA's logic of picking the first CPU port as the CPU port that all user ports are affine to, by default. An upcoming change would like to influence DSA's selection of the default CPU port to no longer be the first one, and in that case, this logic needs adaptation. Since there is no observed leakage or duplication of frames if all CPU ports are defined in this bit mask, simply include them all.
