5907675a47 Add AC state change hook
And start wiring to x86_power so it can detect AC state changes
(needed to enable/disable turbo).

*YES*, this compiles for BDS/Daisy now...

1655c8727a Add hooks for chipset power transitions
This is cleaner than having x86_power explicitly know about everything
else in the system that cares about power transitions.

TEST=boot and shutdown system; still works.  Mouse powered to system is off in S5.

13ad1c007b Implement HOOK_SYSJUMP and use it to preserve LPC host event mask
This also changes shared_mem to use all the remaining RAM, instead of
reserving a fixed-size buffer.

hostevent  --> all masks should be 0
hostevent smi 0x12300000
hostevent  --> should confirm SMI mask was set
sysjump b
hostevent  --> should confirm SMI mask is still set
reboot

This covers modules which need to initialize before task_start(), but
don't particularly care in what order they're initialized.

70f3fcaf86 Add hooks module so modules can be notified of system-level events.
This will be used for sleep/wake/sysjump/etc.  For now it's just wired
up to clock frequency changing.
