net: dsa: bcm_sf2: add function finding RGMII register
Simple macro like REG_RGMII_CNTRL_P() is insufficient as:
1. It doesn't validate port argument
2. It doesn't support chipsets with non-lineral RGMII regs layout
Missing port validation could result in getting register offset from out
of array. Random memory -> random offset -> random reads/writes. It
affected e.g. BCM4908 for REG_RGMII_CNTRL_P(7).
Fixes: a78e86ed586d ("net: dsa: bcm_sf2: Prepare for different register layouts")
