irq_chip.end got obsolete with the removal of __do_IRQ().

irq-mb93093.c even lacks an implementation, but nobody noticed that
it's broken since commit 88d6e1 in 2006.

Make use of the new features in genirq:

1) Set the chip flag IRCHIP_EOI_IF_HANDLED, which ensures in the
   core code that irq_eoi() is only called when the interrupt was
   handled. That removes the extra status check in the callback.

2) Use the preflow handler, which is called from the fasteoi core code
   before the device handler. That avoids another status check and the
   open coded handler redirection.

The new core code allows to update the type in irq_data and return
IRQ_SET_MASK_OK_NOCOPY, so the core code will not touch it, except for
setting the IRQ_LEVEL flag.

Retrieve the IRQ_LEVEL information from irq_data which avoids a

This includes conversion to new style irq_chip functions, and
correctly enabling/disabling per-CPU interrupts.

The hardware interrupt bit to irq number mapping is now done with a
flexible map, instead of by bit twiddling the irq number.
