Subject: ARM: OMAP: Split uncompress.h to mach-omap1 and mach-omap2

This allows us to eventually move omap2+ to generic
debug code that's configured in Kconfig for the port.

Subject: ARM: OMAP: Split plat/serial.h for omap1 and omap2+

For omap1, we'll keep mach/serial.h around for 8250.c hardware
workarounds. For omap2+, we no longer need mach/serial.h and
can make it local to mach-omap2.

Subject: ARM: OMAP2+: Fix relative includes for serial.h

As discussed on linux-arm-kernel, we want to avoid
relative includes for the arch/arm/*omap* code:

http://www.spinics.net/lists/linux-omap/msg80520.html

Fix serial.h by moving it to mach/serial.h.

Subject: ARM: OMAP: Remove NEED_MACH_GPIO_H

Omap no longer needs this option, mach/gpio.h is
empty.

Also remove mach/irqs.h from gpio-omap.h and
include it directly from the related omap1
gpio init files.

Otherwise omap2+ build fails for MULTI_PLATFORM.
