Hello,

This patch series adds initial support for the MediaTek MT7628 Embedded
Switch.

The driver implements the basic functionality required to operate the
switch using DSA. The hardware provides five internal Fast Ethernet user
ports and one Gigabit port connected internally to the CPU MAC.

Bridge offloading is not yet supported.

Tested on an MT7628NN-based board.

changes since v2:
- fix binding issues found in review
- fix ignored dsa_tag_8021q_register return value
- add switch teardown to clean up tag_8021q
- fix ordering issue where mdio probe fail would leak tag_8021q

changes since v1:
- changed port 6 phy-mode to internal
- cleaned up tag_mt7628 rcv function and mask defines
- fixed sorting error in drivers/net/dsa/ Kconfig and Makefile
- fixed sorting error in net/dsa/ Kconfig and Makefile
- fixed mt7628_mii_read/write return values on error
