Now that the only field in struct sys_timer is .init, delete the struct,
and replace the machine descriptor .timer field with the initialization
function itself.

This will enable moving timer drivers into drivers/clocksource without
having to place a public prototype of each struct sys_timer object into
include/linux; the intent is to create a single of_clocksource_init()
function that determines which timer driver to initialize by scanning
the device dtree, much like the proposed irqchip_init() at:

This patch moves the platform data definition from

This change should make no functional change to the PXA code. The move

  imote2_defconfig pxa3xx_defconfig spitz_defconfig zeus_defconfig

1) Made every part modular, components are not built in if not selected.
2) Removed loads of preprocessor goo, mostly "#ifdef MACH_AKITA .... #endif" and
   similar code. The kernel size will grow by a few kb now, but the file is much
   more readable.
3) Reworked SD/CF power setting function and made it reentrant.

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.

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.

Borzoi, Terrier and Akita use the same NAND Flash OOB layout, which
seems to be different from Spitz for some reason. Here is a fix.

When the code was ported to the platform data, the map was applied just
for Akita.

After this patch, Flash works again on Borzoi. Terrier still has a
problem with partition table different from Borzoi (unfixable without
reading of the system configuration in flash) and JFFS2 partitions can
be mounted (with some "Empty flash at ... ends at ..." in the syslog).
