Function RTMPSetPICMode

RTMPSetPICMode reverts from APIC mode to legacy PIC mode:

void RTMPSetPICMode(void);

All IOAPICs are disabled and the legacy i8259 interrupt controllers are reenabled. Note that IRQs of PCI devices are not reset to their boot state, so this function must not be called when PCI devices drivers are still active.

It is generally not recommended to call this function. An application which has switched to APIC mode using RTMPSetAPICMode should stay in APIC mode until it is rebooted.
