These patches were developed when testing upstream Linux with OpenBMC on
Romulus. We need to ensure the LPC clock is enabled, now that the clock
driver turns off any unused clocks. We also need to enable the LPC
firmware cycles bit as we do not intend to upstream any mach-aspeed
hacks.

There was no existing binding document for the LPC host interface
controller, so I wrote one that includes the required clock description.
