mpc8[5/6]xx: Ensure POST word does not get reset
The POST word is stored in a spare register in the PIC on MPC8[5/6]xx processors. When interrupt_init() is called, this register gets reset which resulted in all POST_RAM POSTs not being ran due to the corrupted POST word. To resolve this, store off POST word before the PIC is reset, and restore it after the PIC has been initialized.
