Subject: [PATCH v2] drivers/misc: (aspeed-lpc-snoop): Add ast2400 to compat

This driver can be used on the aspeed ast2400 with minor
modifications.

Tested: ast2400 on quanta-q71l

Signed-off-by: Patrick Venture <venture@...gle.com>
---
v2: added aspeed-g5 area because ast2400 doesn't use those bits.
    also updated commit message.
