In  the final versions of the Porter board (called "PORTER_C") Renesas
decided to get rid  of the Maxim Integrated MAX3355 OTG chip and didn't
add any other provision to differ the host/gadget mode, so we'll have to
remove  no longer valid "renesas,enable-gpio" property from the HS-USB
device node.  Hopefully, the earlier revisions of the board were never
seen in the wild...

Renesas sound driver needs #sound-dai-cells settings, but, this usage
is a little bit confusable. It came from ALSA SoC historical reasons.
The sound DAI naming method is different between Single/Multi DAI in
the ALSA framework, and it is used for sound card matching.
And this #sound-dai-cells has relationship to it.
Current SoC dtsi has #sound-dai-cells = <1> as default settings
(= it is assuming that board/platform has multi DAI), and
board/platform side needs to overwrite it if board/platform was single
DAI. This style is more confusable for users.
This patch removes SoC side default settings, and force to set it by
board/platform side.

The default value of #sound-dai-cells in r8a7778.dtsi is one, while
the /sound/simple-audio-card,cpu device node in r8a7778-bockw.dts uses a
phandle without any extra cells ("<&rcar_sound>"), causing:

    /sound/simple-audio-card,cpu: arguments longer than property
    asoc-simple-card sound: parse error -22
    asoc-simple-card: probe of sound failed with error -22

Override #sound-dai-cells to zero to fix this.

22b16071 ("ARM: shmobile: alt: Add pfc pins to DT") introduced pfc pins
to the alt device tree but did not reference them. This patch fixes ether
pfc by:

* Referencing ether pins
* Adding and referencing phy1 pins
* Removing ether b pins. These are not used in the configuration
  of the alt board used for testing and empirically their presence
  prevents ethernet from functioning correctly in that environment.
