1c552eb44d bmips: add basic BCM6358 ethernet support
The MDIO bus is supported but there are errors when trying to probe and
configure the external BCM5325E switch through B53 DSA.
Therefore, let's add basic ethernet (but working) support for now.

4165e565d2 bmips: switch to upstream ehci overcurrent flag
After backporting upstream ehci overcurrent patches we need to use spurious-oc
instead of ignore-oc.

7f04d67517 bmips: add experimental PCI/PCIe support
These PCI drivers are a bit hacky and definitely not suitable for upstreaming,
but hopefully we can use them as a base for developing proper upstream PCI
drivers.

029093a302 bmips: add new target
This target has full device tree support, thus reducing the number of
patches needed for bcm63xx, in which there's a patch for every board.

The intention is to start with a minimal amount of downstream patches and
start upstreaming all of them.

Current status:
 - Enabling EHCI/OHCI on BCM6358 causes a kernel panic.
 - BCM63268 lacks Timer Clocks/Reset support.
 - No PCI/PCIe drivers.
 - No ethernet drivers.
