Writing '1' to particular bit of IRQENABLE_CLEAR register disables the corresponding interrupt on revision 2 LCDC. This register was wrongly configured to disable all previous enabled interrupts instead of disabling only palette completion interrupt. Patch fixes it by clearing only palette completion interrupt bit.
