clk_add_alias is commonly called for platform devices that are not yet
registered in the device tree. Thus the clock alias is associated with
NULL device name. Fix this by passing the device name instead of just
device pointer.

The remaining registers are separated into:

   - <mach/regs-ost.h>
   - <mach/regs-rtc.h>
   - <mach/regs-intc.h>

and then we can remove pxa-regs.h completely. Instead of #include this
file, let's:

1. include the specific <mach/regs-*.h> with care (if that's absolutely
   necessary)

2. define the registers in the driver, make cleanly defined API to expose
   the register access to external with sufficient reason

The definitions of PXA_CS<x>_PHYS are really PXA2xx specific and should
be moved out of pxa-regs.h. As an illustration, the PXA3xx static chip

This isn't perfect but at least solves the problem of pm.c's dependency

Move the processor specific initialization (largely resources initialization)
out of soc_common_drv_pcmcia_probe() into dedicated sa11xx_drv_pcmcia_probe()
and __pxa2xx_drv_pcmcia_probe().

By doing this, we are now able to move the PCMCIA related definitions out of
pxa-regs.h and back into pxa2xx_base.c.

As a result, remove that reference of _PCMCIA1IO in arch/arm/mach-pxa/viper.c.

The only things prevent drivers/serial/pxa.c from being generic enough
are:

  1. IER_UUE which can be safely replaced by UART_IER_UUE as defined in
     serial_reg.h for PXA

  2. __PREG() and FFUART/BTUART/STUART definitions to decide the UART
     port name

And removed the un-necessary #include of <mach/...> and <asm/...> headers.

Let's handle GPIOs by banks, each bank covers up to 32 GPIOs with one set
of registers, and each set of registers start from different offsets.

           GPLR    GPDR    GPSR    GPCR    GRER    GFER    GEDR
 BANK 0 - 0x0000  0x000C  0x0018  0x0024  0x0030  0x003C  0x0048
 BANK 1 - 0x0004  0x0010  0x001C  0x0028  0x0034  0x0040  0x004C
 BANK 2 - 0x0008  0x0014  0x0020  0x002C  0x0038  0x0044  0x0050

 BANK 3 - 0x0100  0x010C  0x0118  0x0124  0x0130  0x013C  0x0148
 BANK 4 - 0x0104  0x0110  0x011C  0x0128  0x0134  0x0140  0x014C
 BANK 5 - 0x0108  0x0114  0x0120  0x012C  0x0138  0x0144  0x0150

 NOTE:
   BANK 3 is only available on PXA27x and later processors.
   BANK 4 and 5 are only available on PXA935

1. introduce GPIO_BANK(n) for the offset base of each bank

2. 'struct pxa_gpio_chip' is expanded to include IRQ edge and mask
   setings, and saved register values as well, and is dynamically
   allocated due to possible bank number ranging from 3 to 6

3. all accesses to GPIO registers are made through 'regbase' within
   'pxa_gpio_chip', and register offset

4. introduce several inline functions to simplify the code a bit

5. change IRQ demux handler to base on gpio chips

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

1. Driver code where pxa_request_dma() is called will most likely
   reference DMA registers as well,  and it is really unnecessary
   to include pxa-regs.h just for this. Move the definitions into
   <mach/dma.h> and make relevant drivers include it instead of
   <mach/pxa-regs.h>.

2. Introduce DMAC_REGS_VIRT as the virtual address base for these
   DMA registers. This allows later processors to re-use the same
   IP while registers may start at different I/O address.

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>
    <mach/pxa2xx-regs.h>
    <mach/pxa3xx-regs.h>
    <mach/mfp.h>
    <mach/mfp-pxa2xx.h>
    <mach/mfp-pxa25x.h>
    <mach/mfp-pxa27x.h>
