After OMAP1 IRQ definitions have been changed by commit 685e2d08c5
("ARM: OMAP1: Change interrupt numbering for sparse IRQ") introduced
in v4.2, ams-delta FIQ handler which depends on them no longer works
as expected. Fix it.
Created and tested on Amstrad Delta against Linux-4.7-rc3

Change interrupt numbering for sparse IRQ. We do this using
a fixed offset until we can drop irqs.h once all it's users
have been updated.
Note that this depends on the GPIO fix for the MPUIO IRQs
"gpio: omap: Fix regression for MPUIO interrupts".
Also note that this patch adds some extra irq alloc warnings
that will go away when we stop calling irq_alloc_descs
in gpio-omap.c with a follow-up patch.

There's no need to have these in plat/io.h.
While at it, clean up the includes to group them
like they typically are grouped.

This patch introduces a Fast Interrupt Request (FIQ) handler for Amstrad Delta
(E3) videophone. The handler's purpose is to process interrupts generated by a
GPIO line that a serial keyboard clock hangs off. It collects consecutive bits
into words, pushing them into a buffer, then requests a higher level interrupt
after one or more words are ready for further processing by a keyboard port
driver.
The handler also processes interrupts generated by two other GPIO lines, used
by other on-board supported devices, by simply requesting a higher level
interrupt, that in turn should invoke those device's specific irq handlers.
IRQ12 line, not used by OMAP1510 hardware (described as reserved), has been
choosen as a higher level interrupt source.
