Use the new functions introduced into the EC driver to support
performing EC software sync via vboot callbacks.
NOTE: This patch assumes that the EC image is added to CBFS
uncompressed. Streaming decompression of the image will be added in a
future patch.
Also adds a new Kconfig option VBOOT_EARLY_EC_SYNC. The new Kconfig
option compiles EC software sync into romstage, dependent upon having a
CrOS EC.
