[ARM] pxa: add basic support for HP iPAQ h5000

This patch adds HP iPAQ h5000's (h5400, h5500) basic definitions.

Kernel will able to boot, work via serial console, mount filesystems
placed on flashes and run USB gadgets (g_ether by default).

Other device drivers (frame buffer, LCD, touchscreen, backlight,
bluetooth, w1/battery, ...) are depend on SAMCOP and MediaQ
SoCs/MFDs, drivers to which will be submitted too, after massive
cleanups.

This machine will be used as "real user" for these new drivers.

This is an updated version of the patch, which contains fixes proposed on
linux-arm-kernel mailing list.

   will be treated as one of the pxa25x variants, and board code

Introduce pxa26x_init_irq() for the second purpose, and treat the
additional GPIOs > 85 on PXA25x specially.

Kconfig option CONFIG_CPU_PXA26x is introduced to optimize the code
a bit when PXA26x support isn't needed. Board config options have
to select this to enable the support for PXA26x.
