superiotool/ite: Add IT8784E support

IT8784E is basically a IT8786E stripped from serial ports 3-6.
There are very few minor register differences in EC IO space and GPIO
LDN, which are covered by this patch.

Based on IT8784E-I Preliminary Specification V0.7.1 (non-public).

TEST=Dump SIO configuration on Protectli VP4670 (vault_cml).
