ARM: OMAP: Fix get_irqnr_and_base to clear spurious interrupt bits
On omap24xx, INTCPS_SIR_IRQ_OFFSET bits [6:0] contains the current
active interrupt number.
However, on 34xx INTCPS_SIR_IRQ_OFFSET bits [31:7] also contains the
SPURIOUSIRQFLAG, which gets set if the interrupt sorting information
is invalid.
If the SPURIOUSIRQFLAG bits are not ignored, the interrupt code will
occasionally produce a bunch of confusing errors:
irq -33, desc: c02ddcc8, depth: 0, count: 0, unhandled: 0
->handle_irq(): c006f23c, handle_bad_irq+0x0/0x22c
->chip(): 00000000, 0x0
->action(): 00000000
Fix this by masking out only the ACTIVEIRQ bits. Also fix a
confusing comment.
