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
