        ARM: OMAP4: PRM: use PRCM interrupt handler
    
    introduced the PRCM interrupt handler and thus the need
    for 64 more interrupts. Since SPARSE_IRQ is still not fully
    functional on OMAP, the NR_IRQS needs to be updated to avoid
    the failure that happen during irq_alloc_descs call inside
    the PRCM driver:
    
    [    0.208221] PRCM: failed to allocate irq descs: -12
    
    Later the mux framework is then unable to request an IRQ from
    the PRCM interrupt handler.
    
    [    1.802795] mux: Failed to setup hwmod io irq -22
    
    Fix that by adding 64 more interrupts for OMAP2PLUS config.
