net: spacemit: Add K1 Ethernet MAC 



The Ethernet MACs found on SpacemiT K1 appears to be a custom design
that only superficially resembles some other embedded MACs. SpacemiT
refers to them as "EMAC", so let's just call the driver "k1_emac".

Supports RGMII and RMII interfaces. Includes support for MAC hardware
statistics counters. PTP support is not implemented.

	  say Y.

	  the kernel: saying N will just cause the configurator to skip all
