net: stmmac: dwmac-loongson: Add Loongson-2K3000 support

This series add stmmac driver support for Loongson-2K3000/Loongson-3B6000M,
which introduces a new CORE ID (0x12) and a new PCI device ID (0x7a23). The
new core reduces channel numbers from 8 to 4, but checksum is supported for
all channels.
====================

Note that the first patch of the series has been merged separately as
commit f438eee2c8c9 ("net: stmmac: dwmac-loongson: Move queue number init
to common function")
