On K3 AM654x/J721E platforms the Port MII mode selection register(s) have
similar format and placed in the System Control Module (SCM) module
sequentially as one register per port, but, depending SOC and CPSW
instance, the base offset and number of ports can be different.

Hence, add possibility to retrieve number of ports and base registers
offset from DT and support for max possible number of ports supported by K3
SoCs like J721E.

There were some problem in ipq8074 Gen2 PCIe phy init sequence.

1. Few register values were wrongly updated in the phy init sequence.
2. The register QSERDES_RX_SIGDET_CNTRL is a RX tuning parameter
   register which is added in serdes table causing the wrong register
   was getting updated.
3. Clocks and resets were not added in the phy init.

Fix these to make Gen2 PCIe port on ipq8074 devices to work.
