Subject: [PATCH 0/3] SD+USB perf/DMA fixes
 
A large part of why the emmc & dwc2 usb
controllers haven't been working properly is
because the "bus" _DMA was incorrectly tagged
as a consumer, when it needs to be a producer.

That is why linux has been dropping the
translation value portions of _DMA().

Since the emmc2 dma (with the old B0 SoC), and the
dwc2 is expected to work, lets add matching 30 bit
IORT entries for them.

Finally, in the shuffle the high speed cap bit override
was dropped from the linux patches, and I failed
to add it back to the firmware values, this caused
the wifi perf to be lower than it should have been.

  Platform/RaspberryPi/Acpitables: Enable Arasan hispeed mode
  Platform/RaspberryPi/AcpiTables: Add further named components
  Platform/RaspberryPi/AcpiTables: Correct _DMA consumer
