Tag the 1,2GHz OPP as suspend OPP to be set before going in suspend mode,
for the G12A, G12B and SM1 SoCs.
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.

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.

Queued patches 1, 3 for v5.4.
The SM1 patch has a dependency on the SM1 DVFS series, which in turn has
a dependency on clock changes. Once I get a stable tag for the SM1
clock changes, I'll queue up the rest.

FYI... I decided not to queue these for v5.4.
I'm pretty sure we'll need these, but I I think we need to do a bit more
suspend/resume testing to be sure we have the right OPPs. here.
For now, this series is in my `v5.4/testing` branch, which is included
in `integ` so it can get a bit broader testing.
