mb/prodrive/atlas: Add Kconfig option to enable SaGv
It turns out that one can use Kconfig options to specify values for
devicetree options, as long as the resulting expression is a compile
time constant. Use this to configure SaGv for Atlas: enable it by
default, but allow SaGv to be disabled manually for convenience when
testing. Enabling SaGv makes MRC train the RAM multiple times, which
takes a significant amount of time.
For further info on SAGV on ADL, please refer to Intel Doc 655258
(Alder Lake Datasheet) section 5.1.3.2.
