Why not make mseon8b_dwmac_mask_bits() a wrapper around
clrsetbits_le32() whose purpose is only to dereference dwmac->regs and
pass it to clrsetbits_le32()? That would be far less changes to review
and audit for correctness, same goes with every other patch in this
series touching the meson drivers.
