This patch adds support for r8a7743/5 SoCs. The Renesas RZ/G1[ME]
(R8A7743/5) usbhs is identical to the R-Car Gen2 family.

No driver change is needed due to the fallback compatible value
"renesas,rcar-gen2-usbhs".
Adding the SoC-specific compatible values here has two purposes:
  1. Document which SoCs have this hardware module,
  2. Allow checkpatch to validate compatible values.

For the case where an external VBUS is used, we should enable the external
VBUS comparator in the driver. This would prevent an unnecessary
overcurrent error which would then disable the host port.

This patch uses the standard 'disable-over-current' binding to allow of the
option of disabling the over-current condition.

The dummy-hcd driver doesn't support emulation of isochronous
transfers.  Therefore it doesn't need to export isochronous endpoint
descriptors; they can be commented out.

Also, the comments in the source code don't express clearly enough the
fact that isochronous isn't supported.  They need to be more explicit.

Finally, change the error status value we use (in theory) for
isochronous URBs.  checkpatch complains about ENOSYS; EINVAL is more
appropriate (it is documented to mean "ISO madness").

Part of the emulation performed by dummy-hcd is accounting for
bandwidth utilization.  The total amount of data transferred in a
single frame is supposed to be no larger than an actual USB connection
could accommodate.

Currently the driver performs bandwidth limiting only for bulk
transfers; control and periodic transfers are effectively unlimited.
(Presumably drivers were not expected to request extremely large
control or interrupt transfers.)  This patch improves the situation
somewhat by restricting them as well.

The emulation still isn't perfect.  On a real system, even 0-length
transfers use some bandwidth because of transaction overhead
(IN, OUT, ACK, NACK packets) and packet overhead (SYNC, PID, bit
stuffing, CRC, EOP).  Adding in those factors is left as an exercise
for a later patch.
