The mach/hardware.h is included in lots of places, and it provides
three different things on pxa:
- the cpu_is_pxa* macros
- an indirect inclusion of mach/addr-map.h
- the __REG() and io_pv2() helper macros
Split it up into separate <linux/soc/pxa/cpu.h> and mach/pxa-regs.h
headers, then change all the files that use mach/hardware.h to
include the exact set of those three headers that they actually
need, allowing for further more targeted cleanup.
linux/soc/pxa/cpu.h can remain permanently exported and is now in
a global location along with similar headers. pxa-regs.h and
addr-map.h are only used in a very small number of drivers now
and can be moved to arch/arm/mach-pxa/ directly when those drivers
are to pass the necessary data as resources.

As Lubbock now provides GPIOs via gpiolib for controlling the socket
power, we can use the MAX1600 driver. Switch Lubbock to use this
driver, which simplifies the code.

On lubbock board, the probe of the driver crashes by dereferencing very
early a platform_data structure which is not set, in
pxa2xx_configure_sockets().

When testing Lubbock, it was noticed that the sa1111 pcmcia driver bound
but was not functional due to no sockets being registered. This is
because the return code from the lowlevel board initialisation was not
being propagated out of the probe function. Fix this.
