[PATCH 3/3] arm64: dts: meson-g12b: specify suspend OPP

[Neil Armstrong]

Tag the 1,2GHz OPPs as suspend OPP to be set before going in suspend mode.

It has been reported that using various OPPs can lead to error or
resume with a different OPP from the ROM, thus use this safe OPP as
it is the default OPP used by the BL2 boot firmware on the 2 clusters.
