Convert DMA library into DMA platform driver and make use of
platform data provided by hwmod data base for OMAP2+ onwards.

For OMAP1 processors, the DMA driver in mach-omap uses resource
structures for getting platform data.

Thanks to Tony Lindgren <tony@atomide.com> for fixing various
omap1 issues and testing the same on OSK5912 board.

Implement errata handling to use flags instead of cpu_is_* and
cpu_class_* in the code.

The errata flags are initialized at init time and during runtime we are
using the errata variable (via the IS_DMA_ERRATA macro) to execute the
required errata workaround.

Reused errata handling patch from: Peter Ujfalusi
<peter.ujfalusi@nokia.com>
https://patchwork.kernel.org/patch/231191/

Changes to above patch:
1. Changes are done for converting all the existing errata work arounds
to use this feature.
2. Detailed description for each errata is added.
3. Fixed bug in SET_DMA_ERRATA macro
4. Bit shifting in macro definitions are replaced with BIT() macro

Prepare DMA library to get converted into DMA driver using platform
device model and hwmod infrastucture(for omap2+, resource structures
for omap1)

The low level read/write macros are replaced with static inline
functions and register offsets are handled through static register
offset tables mapped through  enumeration constants.

These low level read/write functions along with static register offset
tables will be moved to respective mach-omap dma files in the later
patches of this series.

There are no functionality changes with these changes except change in
logic for handling 16bit registers of OMAP1.

The install_special_mapping routine (used, for example, to setup the
vdso) skips the security check before insert_vm_struct, allowing a local
attacker to bypass the mmap_min_addr security restriction by limiting
the available pages for special mappings.

bprm_mm_init() also skips the check, and although I don't think this can
be used to bypass any restrictions, I don't see any reason not to have
the security check.

rather more complex patch which changed the name according to the chip

a good idea (however fun) this is a simple alternative.
