Cortex-M7: Add support for enabled the D-Cache in write only mode.
...
SAMV7 Ethernet: I- and D-Cache are now enabled in the netnsh/ configuration. D-Cache is enabled in write-though mode. This mode is necessary because the DMA descriptors are each 8-bytes in size but the D-Cache cache line is 32-bits in size. So it is impossible make coherency for every 8-byte DMA descriptor without write-through.

SAMV7 EMAC: Fix alignment issue: RX buffers need to be invalidated. This means the alignment of buffers must be at least to the data cache line size at both ends of the buffer

SAMV7 EMAC: Sometimes TX is not started when TSTART is set??? Workaround seems to be to set it twice. Restored full optimization. Also CONFIG_NET_NOINTS is set so that interrupt level provessing is avoided
