arm64: dts: ti: k3-j721e-sk: Add DT nodes for power regulators
[ Upstream commit 97b67cc102dc2cc8aa39a569c22a196e21af5a21 ]
Add device tree nodes for two power regulators on the J721E SK board.
vsys_5v0: A fixed regulator representing the 5V supply output from the
LM61460 and vdd_sd_dv: A GPIO-controlled TLV71033 regulator.
