kernel: add more dsa b53 pending patches

Browse Source 
These patches have now received a positive review upstream, so let's add them
to pending patches.

776-net-dsa-b53-mmap-add-phy-ops.patch:
  This is mostly bmips/bcm63xx-specific to get external switches working
  without hanging the device when accessing certain registers.

777-net-dsa-b53-mdio-add-support-for-BCM53134:
  This adds support for BCM53134 switch on DSA B53, so any target using DSA B53
  can benefit from it.

Also fix sercomm-h500-s external switch IMP port phy-mode.

Subject: [PATCH] net: dsa: b53: mmap: disable phy read/write ops
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
B53 MMAP switches have a MDIO Mux bus controller which should be used instead
of phy_read() and phy_write() ops.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Add support for the BCM53134 Ethernet switch in the existing b53 dsa driver.
The BCM53134 is very familiar to the BCM58XX series.

Implement phy_read16() and phy_write16() ops for B53 MMAP to avoid accessing
B53_PORT_MII_PAGE registers which hangs the device.
This access should be done through the MDIO Mux bus controller.
