irqchip: spear_shirq: Remove the parent irq "ack"/unmask

"ack" is actually a mask in the parent irq. The demultiplexer and the
handlers run with interrupts disabled. No point in masking and
unmasking the parent.

I don't know if there are less efficient ways to code that. Get rid of

None of the chips has a ACK register. The code brainlessly fiddles
with the enable register, so it might even reenable a disabled
interrupt at least on spear300.

irqchip: spear_shirq: Fix interrupt offset

The ras3 block on spear320 claims to have 3 interrupts. In fact it has
one and 6 reserved interrupts. Account the 6 reserved to this block so
it has 7 interrupts total. That matches the datasheet and the device
tree entries.
