For some platforms, it is inappropriate to register all PXA UARTs.
In some cases, the UARTs may not be used, and in others we may want
to avoid registering the UARTs to allow other drivers (eg, FICP) to
make use of the UART.

In addition, a while back there was a request to be able to pass
platform data to the UART driver.

This patch enables all of this by providing functions platforms can
call to register each individual UART.

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,

Considering the header mess ATM, it is not always possible to include
the correct header files within board code. Let's keep this simple:

  <mach/pxa25x.h>  - for pxa25x based platforms
  <mach/pxa27x.h>  - for pxa27x based platforms
  <mach/pxa300.h>  - for pxa300 based platforms
  <mach/pxa320.h>  - for pxa320 based platforms
  <mach/pxa930.h>  - for pxa930 based platforms

NOTE:

1. one header one board file, they are not compatible (i.e. they have
   conflicting definitions which won't compile if included together).

2. Unless strictly necessary, the following header files are considered
   to be SoC files use _only_, and is not recommended to be included in
   board code:

    <mach/hardware.h>
    <mach/pxa-regs.h>

Original patch from Marek Vasut, the problems with PXA26x are:

1. there are additional 4 GPIOs 86,87,88,89 have their direction bits
   inverted in GPDR2, as well as their alternate function bits being
   '1' for their GPIO functionality in GAFRx

2. there is no easy way to decide if the processor is a pxa26x or a
   pxa250/pxa255 at run-time, so the assumption here is the pxa26x
   will be treated as one of the pxa25x variants, and board code
   should have a better knowledge of the processor it is featured

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.

__gpio_is_inverted() will be optimized way when CONFIG_CPU_PXA26x
isn't selected.
