BeagleBoardPkg: Ensure there is no pending IRQ and disable timer
When the BeagleBoard UEFI is started from a 1st (or 2nd stage) boot loader it is possible there are still some pending IRQ. Clean the interrupts before starting the BeagleBoard UEFI. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@12034 6f19259b-4bc3-4df7-8a09-765794883524
