"omap: iovmm: don't check 'da' to set IOVMF_DA_FIXED flag",
changes iovmm to receive flags specified by user, however
the upper 16 bits of the flags are wiped by iovmm itself.
This fixes IOVMF_DA_FIXED flags from being lost, and lets the user
map its desired "device addresses".

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,
as the board/SoC is scheduled for removal.

To be able to relocate the .bss section at run time independently from
the rest of the code, we must make sure that no GOTOFF relocations are
used with .bss symbols. This usually means that no global variables can
be marked static unless they're also const.
Let's remove the static qualifier from current offenders, or turn them
into const variables when possible. Next commit will ensure the build
fails if one of those is reintroduced due to otherwise enforced coding
standards for the kernel.

Header files in arch/arm/*/include/mach included from
arch/arm/include/asm/*.h are there to provide necessary definitions for
either the rest of the kernel or the ARM specific parts. They shouldn't
be polluted with *any* platform private stuff which is not absolutely
necessary to satisfy the rest of the kernel.
Hence move the OMAP specific SMP boot functions to different header
instead of keeping them in 'plat/smp.h' which gets included indirectly
by linux/smp.h
The patch is outcome of the discussion in below thread:

NOTE!
This merge commit was created to fix compilation error. The block
tree was merged upstream and removed the 'elv_queue_empty()'
function which the new 'mtdswap' driver is using. So a simple
merge of the mtd tree with upstream does not compile. And the
mtd tree has already be published, so re-basing it is not an option.
To fix this unfortunate situation, I had to merge upstream into the
mtd-2.6.git tree without committing, put the fixup patch on top of
this, and then commit this. The result is that we do not have commits
which do not compile.
In other words, this merge commit "merges" 3 things: the MTD tree, the
upstream tree, and the fixup patch.

Currently IOVMM driver sets IOVMF_DA_FIXED/IOVMF_DA_ANON flags according
to input 'da' address when mapping memory:
da == 0: IOVMF_DA_ANON
da != 0: IOVMF_DA_FIXED
It prevents IOMMU to map first page with fixed 'da'. To avoid such
issue, IOVMM will not automatically set IOVMF_DA_FIXED. It should now
come from the user throught 'flags' parameter when mapping memory.
As IOVMF_DA_ANON and IOVMF_DA_FIXED are mutually exclusive, IOVMF_DA_ANON
can be removed. The driver will now check internally if IOVMF_DA_FIXED
is set or not.

omap_dsi_set_vc_id() takes the omap_dss_device pointer, the Virtual Channel
