Update the B53 driver to support VLANs while not filtering. This requires us to enable VLAN globally within the switch upon driver initial configuration (dev->vlan_enabled). We also need to remove the code that dealt with PVID re-configuration in b53_vlan_filtering() since that function worked under the assumption that it would only be called to make a bridge VLAN filtering, or not filtering, and we would attempt to move the port's PVID accordingly. Now that VLANs are programmed all the time, even in the case of a non-VLAN filtering bridge, we would be programming a default_pvid for the bridged switch ports. We need the DSA receive path to pop the VLAN tag if it is the bridge's default_pvid because the CPU port is always programmed tagged in the programmed VLANs. In order to do so we utilize the dsa_untag_bridge_pvid() helper introduced in the commit before within net/dsa/tag_brcm.c.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
