The HB onboard audio currently makes use of the imx-audio-sgtl5000
binding. This binding does not support auxiliary audio devices such
as external amplifiers. The simple-audio-card binding does support
this property which allows systems incorporating the HB to add an
auxiliary device that's attached to the HB audio jack with an
overlay. Convert the HB onboard audio to use simple-audio-card for
this additional flexibility.

dtc now warns about missing #sound-dai-cells:

Lots of i.MX boards use the SGTL5000 codec, but not all get the warning
because only some reference the codec with "sound-dai" property. However,
the codec should always provide #sound-dai-cells regardless, so fix all
the occurrences.

Pass the memory unit-adress to fix the following build warnings with W=1:
Warning (unit_address_vs_reg): Node /memory has a reg or ranges property, but no unit name
There are cases where dts passes an empty memory node, which will be filled
by the bootloader. Passing the memory base address still allows the
bootloader to fill the memory size.

Name the regulators according to the voltage rails they are feeding in
the schematic. The USB 2-4 regulators are fixed regulators and are always
on, as they are not a VBUS supply for a single USB host port on the i.MX6,
but supply VBUS to ports behind a USB hub and there is currently no way
to model this in mainline.
