net/designware: make driver compatible with data cache
Up until now this driver only worked with data cache disabled.
To make it work with enabled data cache following changes were required:
* Flush Tx/Rx buffer descriptors their modification
* Invalidate Tx/Rx buffer descriptors before reading its values
* Flush cache for data passed from CPU to GMAC
* Invalidate cache for data passed from GMAC to CPU
