Startup code in openhcl_boot should put the APs into the mailbox protocol wait for wakeup state. Corresponding changes in Linux Kernel are required to process and signal mailbox protocol wakeup state for each AP.

This requires openhcl_boot to issue hypercalls, create some pagetables for use for APs, startup the APs in openhcl_boot, and pass the mailbox page address to Kernel in the device tree.
