Add DTS node for LP87334E PMIC and two TPS6287x high current buck
converters.

LP87334E is responsible for supplying power to the MCU and MAIN domains
as well as to LPDDR4. The two TPS6287x supply power to the MAIN
domain for AVS and other core supplies.

Please use subject prefixes matching the subsystem. You can get them for
example with `git log --oneline -- DIRECTORY_OR_FILE` on the directory
your patch is touching. For bindings, the preferred subjects are
explained here:

Node names should be generic. See also an explanation and list of
examples (not exhaustive) in DT specification:
