This patch adds main support for the generic phyCORE-PXA270 CPU module
(aka PCM-027). Its as generic as possible to support any kind of baseboard.

Note: Neither the CPU module nor the pcm027.c implementation can work without
a baseboard support. Baseboard support can be added by the PCM-990 or any
custom variant.

V2:
 After comments by Eric Miao:
  - Currently unsupported devices moved into separate patch
  - direct call of baseboard initialisation

V3:
 After comments by Russell King
  - sort include files
  - setting RTC bit for power control removed
 - style problems fixed (discovered by checkpatch.pl)

This definition produces processor specific code in generic function
pxa_gpio_mode(), thus creating inconsistencies for support of pxa25x
and pxa27x in a single zImage.

As David Brownell suggests, make it a run-time variable and initialize
at run-time according to the number of GPIOs on the processor. For now
the initialization happens in pxa_init_irq_gpio(),  since there is
already a parameter for that, besides, this is and MUST be earlier
than any subsequent calls to pxa_gpio_mode().

1. define PXA_GPIO_IRQ_BASE to be right after the internal IRQs,
   and define PXA_GPIO_IRQ_NUM to be 128 for all PXA2xx variants

2. make the code specific to the high IRQ numbers (32..64) to be
   PXA27x specific

3. add a function pxa_init_irq_high() to initialize the internal
   high IRQ chip, the invoke of this function could be moved to
   PXA27x specific initialization code

1. PXA_IRQ_SKIP is defined to be 7 on PXA25x so that the first IRQ
   starts from zero. This makes IRQ numbering inconsistent between
   PXA25x and PXA27x. Remove this macro so that the same IRQ_XXXXX
   definition has the same value on both PXA25x and PXA27x.

2. make IRQ_SSP3..IRQ_PWRI2C valid only if PXA27x is defined, this
   avoids unintentional use of these macros on PXA25x

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
