Add nodes for TPS6287x present in AM68 SK, AM69 SK and J784S4 EVM. They
are a family of synchronous step-down DC/DC converters. These converters
are used to enable AVS (Adaptive Voltage Scaling) for these devices.

Also since AM68 SK lacks DT node of it's PMIC, LP8733; make use of this
series to add that in as well.

Boot logs (v2): https://gist.github.com/nehamalcom/1a288f534d730e8af43c48a175919b19 

Changes since v1:
- remove changing the compatibility of the existing driver (Rob and
  Mark)
- remove unnecessary bootph-pre-ram, have them only for VDD_CPU_AVS
  (Udit)
