Convert the R-Car M2-W SoC from the old "Renesas R-Car Gen2 Clock Pulse
Generator (CPG)", "Renesas CPG DIV6 Clock", and "Renesas CPG Module Stop
(MSTP) Clocks" DT bindings to the new unified "Renesas Clock Pulse
Generator / Module Standby and Software Reset" DT bindings.
This simplifies the DTS files, and allows to add support for reset
control later.

Revert "ARM: dts: porter: Enable SCIF_CLK frequency and pins"
ARM: dts: r8a7791: Don't disable referenced optional clocks
This reverts commit 19417bd9c5 ("ARM: dts: porter: Enable SCIF_CLK

http://elinux.org/File:R-CarM2-KOELSCH_PORTER-B_PORTER_C_Comparison.pdf
the external oscillator for SCIF_CLK is not mounted on the porter boards.

clk_get on a disabled clock node will return EPROBE_DEFER, which can
cause drivers to be deferred forever if such clocks are referenced in
their clocks property.
Update the various disabled external clock nodes to default to a
frequency of 0, but don't disable them to prevent this.

* Fixed rate and fixed factor clocks do not require an

* Since 07705583e9 ("clk: shmobile: div6: Make clock-output-names

In the above cases there is only one clock output and its name is taken
from that of the clock node. Accordingly, remove the unnecessary
clock-output-names properties and as necessary update the node names.

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remove no longer valid "renesas,enable-gpio" property from the HS-USB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...
