Kconfig: Allow mainboards to disable stage cache
On recent Intel ChromeOS devices, although S3 is still supported, only
S0ix is used on user devices, so we don't care about optimising S3
resume time. Disabing the stage cache saves boot time at the cost of
increasing the S3 resume time. E.g. on nissa this reduces boot time by
6 ms and increases S3 resume time by 89 ms.
BUG=b:247940538, b:192032803
TEST=Build and boot on nissa with MAINBOARD_DISABLE_STAGE_CACHE
selected.
