This patch moves some attributes out from the platform data into the
dynamically created nand device.   This results into a cleaner interface
and allows to use constant pxa3xx_nand_flash definitions.

This patch marks some attributes as 'const' which are set only once and
never be modified by the driver.  There are some changes in parameter
list and variable declarations too which mark them as 'const'.

This patch adds 'flash' and 'num_flash' attributes to the platform data.
There was added code in the driver to iterate across these attributes in the
detect-flash routine.  This is done similarly to the existing method
which uses a 'builtin_flash_types' field.

This patch moves the exported datastructures from the pxa3xx_nand.c driver
into the <mach/pxa3xx_nand.h> header. This is a plain movement without
any modification of the attributes.

This is the first one of a set of patches which:

 * allows to specify used NAND flash in the platform code and allows to turn
   off the old way to specify NAND characteristics in the driver.  This way did
   not worked well as these characteristics depend on the platform and can not be
   derived from NAND id alone.

   E.g.  some NAND chips share the same ID (e.g.  K9K8G08U0A and K9NBG08U5A) but
   have different timings (which are written in the common driver currently and
   must be modified there).

 * adds 'const' annotations at various places

Further patches will be sent to the mtd-list.

This reverts commit a2bd7274.

It wasn't really right to begin with (there's a better fix for the
problem with e820 reservations clashing with PCI BAR's pending), but it
also actually causes more regressions, so it should be reverted even
before the better fix is finalized.

Rafael reports that this commit broke AHCI detection, and thus causes
the kernel to not boot on his quad core test box.

Using just 'unsigned' will make flags an unsigned int. While this is
arguably not an error on blackfin where sizeof(int) == sizeof(long),
the patch is still justified on the grounds of principle.

The patch was generated using the Coccinelle semantic patch framework.

Ordinarily, memory holes in flatmem still have a valid memmap and is safe
to use. However, an architecture (ARM) frees up the memmap backing memory
holes on the assumption it is never used. /proc/pagetypeinfo reads the
whole range of pages in a zone believing that the memmap is valid and that
pfn_valid will return false if it is not. On ARM, freeing the memmap breaks
the page->zone linkages even though pfn_valid() returns true and the kernel
can oops shortly afterwards due to accessing a bogus struct zone *.

This patch lets architectures say when FLATMEM can have holes in the
memmap. Rather than an expensive check for valid memory, /proc/pagetypeinfo
will confirm that the page linkages are still valid by checking page->zone
is still the expected zone. The lookup of page_zone is safe as there is a
limited range of memory that is accessed when calling page_zone.  Even if
page_zone happens to return the correct zone, the impact is that the counters
in /proc/pagetypeinfo are slightly off but fragmentation monitoring is
unlikely to be relevant on an embedded system.
