Recent changes to PXA PWM support changed the PXA27X PWM device
numbering scheme.

The linux-3.5 PXA PWM driver followed the hardware numbering scheme for
the 4 PWMs, while the linux-3.6-rc1 PXA PWM driver has adopted a linear
numbering scheme:

Address		Hardware	3.5 pwm_id	3.6-rc1 pwm_id
0x40b00000	PWM0		0		0
0x40b00010	PWM2		2		1
0x40c00000	PWM1		1		2
0x40c00010	PWM3		3		3

The hx4700 backlight uses PWM1 at 0x40c00000. Consequently the pwm_id
must be changed from 1 to 2.

This patch fixes the backlight PWM device number and at the same time
moves from the legacy PWM API (pwm_id) to the new PWM API (pwm_lookup).

Basic suspend/resume is fixed by ensuring that the PGSR registers are
set correctly before sleep mode is entered. In particular four of the
active low resets need to be driven high while in sleep mode, otherwise
the unit resets itself instead of suspending. Another problem was that
the PCFR_GPROD bit is set by the HTC bootloader; this caused GPIO reset
(i.e. the reset button) to fail immediately after returning from sleep
mode.

The HP iPAQ hx4700 has 128Mb of flash provided by two Intel StrataFlash devices.
The hx4700 platform configuration defines a single 128Mb flash resource,
resulting in the MTD physmap-flash driver probing the first device only and
presuming the second device is identical:

physmap platform flash device: 08000000 at 00000000
physmap-flash: Found 2 x16 devices at 0x0 in 32-bit bank. Manufacturer ID 0x000089 Chip ID 0x008816
physmap-flash: Found 2 x16 devices at 0x4000000 in 32-bit bank

physmap-flash: 2 set(s) of 2 interleaved chips --> 32 partitions of 4096 KiB

Unfortunately the two devices are not identical. The first has a device ID of
0x8816, identifying a bottom parameter device. The second has a device ID of
0x8813, identifying a top parameter device. By not probing the second device,
physmap-flash does not discover the correct block sizes.

This patch splits the configuration into two 64Mb flash resources, forcing
physmap-flash to probe both devices and thus discover the correct block sizes:

physmap platform flash device: 04000000 at 00000000

The set_vpp() method provided by physmap passes a map_info back to
the platform code, which has little relevance as far as the platform
is concerned (this parameter is completely unused).

Instead, pass the platform_device, which can be used in the pismo
driver to retrieve some important information in a nicer way, instead
of the hack that was in place.

The empty set_vpp function in board-at572d940hf_ek.c is left untouched,

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

In addition, a while back there was a request to be able to pass
