The patch addresses Intel heterogeneous cores as `Efficient` and
`Performance` cores instead of `small` and `big` cores. It is to ensure
coreboot code has uniform reference to the heterogeneous cores. So, the
patch renames all `small` and `big` core references to `efficient` (eff)
and `performance` (perf) cores respectively.

Although S3 is supported on nissa, only S0ix is used on user devices,
so we can ignore optimising the S3 resume time. Disable the stage
cache to save boot time at the cost on increasing the S3 resume time.
Boot time is reduced by ~6 ms. This is mostly from adding postcar to
the stage cache, which is slow since TSEG is not cached in romstage.
Adding ramstage and FSP-S take negligible time.
The S3 resume time is increased by ~89 ms total from loading and
decompressing ramstage and FSP-S.

Now that power sequencing has been implemented, switch from using ACPI
"probed" flag to "detect" flag for all i2c touchscreens. This removes
non-present devices from the SSDT and relieves the OS of the burden of
probing.
BUG=b:121309055
TEST=build/boot Windows/linux on drallion, verify touchscreen functional
in OS, dump ACPI and verify only i2c devices actually present on the
board have entries in the SSDT.
