Subject: [PATCH v3 2/7] arm64: dts: ti: iot2050: Disable R5 lockstep for all PG2 boards

From: Baocheng Su <baocheng.su@...mens.com>

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

As now the Basic PG2 consumes this twice, move Basic disabling to the
PG1 variant.

[Jan: avoid duplication of disabling for Basic PG2]
