arm64: dts: ti: iot2050: Disable R5 lockstep for all PG2 boards

The R5 lockstep disabling should be common for all PG2 boards, move it
from variants dts to common-pg2.dtsi.

arm64: dts: ti: iot2050: Add support for product generation 2 boards

This adds the devices trees for IOT2050 Product Generation 2 (PG2)

The major difference to PG1 is the used silicon revision (SR2.x on
PG2).
