offset 0x0 occupies TX0_QSERDES_TX0_PCIE4(tx0) register but as per
PHY sequence to support gen4X4 we need to use 
TXZ_QSERDES_TXZ_PCIE4_4L_QMP_TXZ for tx.

Here we are using already existing qmp_pcie_offsets_v6_20 offset that 
matches exactly same offsets as sa8775p for gen4x2 . so we are reusing it.
rather creating separate entry.

ok.

Don't you need to provide .tx2 / .rx2 then? qmp_pcie_init_registers()
writes tx2/rx2 regions if (lanes >= 2).

Please either rename v6_20 to v5_20 or add a separate instance (my
preference would be for the latter). We have some duplication around
registers defs and offsets to catch version mismatches.
