fsp/tpo: Enable Timed power on (TPO) support
This patch enabled TPO sequence handling in Sapphire.
Timed power on notification comes from the user through
set_poweron_time tool. After receiving a valid TPO from user,
Sapphire sends a request to FSP through maibox command to set TPO.
FSP will set TPO and power on the system as per the TPO set by the user.
[ Removed global read_data, removed writing to NULL pointers,
fixed a couple of memory leaks ... --BenH
]
