Russell King 46678fbdca mvebu: add uDPU update patches
Update the uDPU kernel support, fixing a number of issues:
* make ethernet work again by adding comphy definitions
* slow the I2C bus to give it more chance of actually working
* the SFP cages are designed to support up to 3W modules, which
  would be prevented from initialising without this patch.

Subject: [PATCH 659/660] arm64: dts: uDPU: SFP cages support 3W modules
The SFP cages are designed to support up to 3W modules, such as G.hn,
G.fast and MoCA modules. Although there is no way for such modules to
declare to software that they consume 3W, we document in DT that this
is the designed power level for these cages.
