[PATCH 01/10] Revert "mfd: cros_ec: Add SCP Core-1 as a new CrOS EC MCU"

[Prashant Malani]

This reverts commit 66ee379d743c69c726b61d078119a34d5be96a35.

The feature flag introduced by Commit 66ee379d743c ("mfd: cros_ec: Add
SCP Core-1 as a new CrOS EC MCU") was not first added in the source EC
code base[1]. This can lead to the possible misinterpration of an EC's
supported feature set, as well as causes issues with all future feature
flag updates.

While this patch modifies drivers/mfd, it would be preferable to submit
it through the chrome-platform tree, since that eliminates cross-tree
dependencies for the series of which this patch is a part.
