superio/ite: Add IT8784E support
IT8784E is basically a IT8786E stripped from serial ports 3-6.
The patch creates a chip directory for IT8784E used by
protectli/vault_cml platforms.
TEST=Boot Ubuntu 22.04 on Protectli VP4670 (vault_cml) and dump the
configuration with superiotool and compare the configuration with
proprietary firmware.
