Cache coherency doesn’t work without enabling this logic.

This series is to enable cache snooping logic in both RC and EP
driver and add the "dma-coherent" property in dtsi to support
cache coherency in 8775 platform.

To verify this series we required [1]

v3 -> v4:
- added new cfg(cfg_1_34_0) for SA8775P in both RC and EP driver.
- populated a flag in the data structures instead of doing
of_device_is_compatible() in both RC and EP patch.
- update commit mesaage and added reveiwed-by tag in commit message
in dtsi patch.
This series looks good now, thanks!
