OMAP: DMA: Introduce errata handling feature
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

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
