armv8: lx2162a: Add Soc changes to support LX2162A

LX2162 is LX2160 based SoC, it has same die as of LX2160 with different packaging. LX2162A support 64-bit 2.9GT/s DDR4 memory, i2c, micro-click module, microSD card, eMMC support, serial console, qspi nor flash, qsgmii, sgmii, 25g, 40g, 50g network interface, one usb 3.0 and serdes interface to support three PCIe gen3 interface.
