macio: Keep interrupt events and CPU IRQ state consistent - #242

Conversation
Apply the Grand Central fixes from dingusdev#240 to O'Hare, Heathrow, and Paddington; the Heathrow ERS shows that it expects to have the same behavior: - Reevaluate the CPU interrupt when either mask changes, releasing it if no pending events remain enabled in either bank (section 7.1). - Keep events latched until software writes InterruptClear, even if a device deasserts its interrupt line or repeats an assertion (sections 7.2.1 and 7.2.5). - Replace writable InterruptMask2 bits instead of ORing them, allowing sources to be disabled while preserving the read-only IntMode bit (section 7.2.6).
