e6000sw: Fix direct register write logic
When accessing a register directly from etherswitchcfg one must specify
a register group(e.g. registers of portN) and the register offset within
the group. The latter is passed as the 5 least significant bits.
Extract the former by dividing the register address by 32, not by 5.
