arm64: ti: dts: Add support for AM62x LP SK
The AM62x LP SK board is similar to the AM62x SK board, but has some not-so-minor changes that requires different device tree. The differences are mainly: - AM62x SoC in the AMC package that meets AECQ100 automotive standard. - LPDDR4 versus DDR4 on the AM62x SK. - TPS65219 PMIC instead of discrete regulators. - IO expander pin names are wired differently. - Second ethernet port is currently disabled as the boards do not have the part physically installed. - OSPI NAND vs OSPI NOR. - No WLAN chip instead a SDIO M.2 connector.
