drivers/intel/fsp2_0: don't select FSP_USES_CB_STACK on FSP 2.0 platform
soc/amd/picasso selected FSP_USES_CB_STACK even though it is FSP 2.0
based, so it doesn't reuse coreboot's stack, but sets up its own stack.
In contrast to all other FSP 2.0 based platforms, this stack isn't in
the CAR region, since AMD Picasso doesn't support CAR and the DRAM is
already available when the x86 cores are released from reset. Selecting
FSP_USES_CB_STACK ended up doing the right thing, but is semantically
wrong. Instead of wrongly selecting FSP_USES_CB_STACK in soc/amd/picasso
we take the corresponding code path if ENV_CACHE_AS_RAM is false which
is only the case for non-CAR platforms.
BUG=b:155501050
TEST=Timeless build results in an identical binary for amd/mandolin,
asrock/h110m-dvs and intel/coffeelake_rvp11 which cover all 3 cases
here.
