[PATCH v1 1/4] arm64: dts: ti: k3-am62p5-sk: Add regulator nodes for AM62P

[Rishikesh Donadkar <r-donadkar@ti.com>]

Add regulator node for AM62P-SK

VCC_3V3_MAIN is the output of LM5141-Q1, and it serves as an input to
TPS22965DSGT which produces VCC_3V3_SYS [1]

VCC_3V3_SYS servers as vin-supply for peripherals like CSI [1].
