The display requires some milliseconds between GPIO_TFT_VA_EN
and GPIO_DISPLAY_ENABLE. Reorder initialisation to comply with
the display spec.
Also tune timings for better compliance with the spec.

Replace sysdev classes and struct sys_device objects used for "core"
power management by the PXA platform code with struct syscore_ops
objects that are simpler.
This reduces the code size and the kernel memory footprint. It also
is necessary for removing sysdevs entirely from the kernel in the
future.

This patch moves the platform data definition from
arch/arm/plat-pxa/include/plat/i2c.h to include/linux/i2c/pxa-i2c.h so
it can be accessed from x86 the same way as on ARM.
This change should make no functional change to the PXA code. The move
is verified by building the following defconfigs:
cm_x2xx_defconfig corgi_defconfig em_x270_defconfig ezx_defconfig
imote2_defconfig pxa3xx_defconfig spitz_defconfig zeus_defconfig
raumfeld_defconfig magician_defconfig mmp2_defconfig pxa168_defconfig
pxa910_defconfig

set_pxa_fb_info() has been a long-standing wart in the naming scheme
of the pxa_set_xxx_info() functions. This renames the function, and
combines set_pxa_fb_parent() with set_pxa_fb_info().

This patch introduces pxa2xx_map_io() and pxa3xx_map_io() to distinguish
between PXA25x/PXA27x and PXA3xx memory mapping.
Also, fixup for platforms broken after introducing pxa{25x,27x}_map_io()
and pxa3xx_map_io() is included.

Since we're now using addruart to establish the debug mapping, we can
remove the io_pg_offst and phys_io members of struct machine_desc.
The various declarations were removed using the following script:
grep -rl MACHINE_START arch/arm | xargs \
sed -i '/MACHINE_START/,/MACHINE_END/ { /\.\(phys_io\|io_pg_offst\)/d }'
[ Initial patch was from Jeremy Kerr, example script from Russell King ]

delay_detect in HZ is confusing, convert it to be millisecond based. And
thus remove those unnecessary call to msecs_to_jiffies() at runtime for
this field. Other constants are converted assuming HZ == 100, which are
basically true for those platforms.
The assignment in csb726.c was incorrect, and is fixed in this patch as
a result.
