[ARM] pxa: move IRQ handling of GPIO 0 and 1 outside of gpio.c

This is part of the work making gpio.c generic enough, the changes
include:

1. move IRQ handling of GPIO 0 and 1 outside (and back into irq.c)

2. pxa_init_gpio() accepts a range for muxed GPIO IRQs, and an IRQ
number for the muxed GPIOs

3. __gpio_is_occupied() and __gpio_is_inverted() are made inline,
and are moved into <mach/gpio.h> instead of generic gpio.c

Due to the problem of reset status bits being handled by different

variable, initialized by SoC-specific code and later being used by
other drivers.

And also introduce clear_reset_status(), which is used to clear the
corresponding status bits. Pass RESET_STATUS_ALL to clear all bits.

[ARM] pxa: separate PXA25x and PXA27x UDC register definitions

The PXA25x and PXA27x USB device controller register definitions are
different. Currently, they live side by side in pxa-regs.h, but only
one set is available depending on the setting of PXA25x or PXA27x.

This means that if we build to support both PXA25x and PXA27x, the
PXA27x definitions are unavailable, even to PXA27x specific code.

Remove these definitions from pxa-regs.h, and place them in separate
files. Include these files where appropriate.

Note: according to the dependencies in drivers/usb/gadget/Kconfig,
we do not support the UDC on PXA27x nor PXA3xx CPUs, so remove the
platform devices from pxa27x.c and pxa3xx.c.

Patch mainly from Eric Miao, with minor edits by rmk.

Note: PWM0 and PWM2 share the same register I/O space and clock gating

PWM0. And this is also true for PWM1/3.

[ARM] pxa: integrate low IRQ chip (ICIP) and high IRQ chip (ICIP2) into one

This makes the code better organized and simplified a bit. The change
will lose a bit of performance when performing IRQ ack/mask/unmask,but
that's not too much after checking the result binary.

This patch also removes the ugly #ifdef CONFIG_PXA27x .. #endif by
carefully not to access those pxa{27x,3xx} specific registers, this
is done by keeping an internal IRQ number variable. The pxa-regs.h
is also modified so registers for IRQ > PXA_IRQ(31) are made public
even if CONFIG_PXA{27x,3xx} isn't defined (for pxa25x's sake)

The incorrect assumption in the original code that internal irq starts
from 0 is also corrected by comparing with PXA_IRQ(0).

"struct sys_device" for the IRQ are reduced into one single device on
pxa{27x,3xx}.
