Unless the DMA mask is set wider than 32 bits, DMA mapping will use a
bounce buffer.

Kernels prior to 5.7 only see the first entry in dma-ranges, so make

Although it is no longer necessary for vchiq's children to have a
different DMA configuration to the parent, they do still need to
explicitly to have their DMA configuration set - to be that of the
parent.

This follows logic in hdmi-codec.c to use speaker layout
from ELD to choose a suitable speaker mapping based on
number of channels requested and signal that in audio
infoframe  and report this back to userspace.

This allows apps like speaker-test and kodi to get the
output to the right speakers.

The new "actpwr" LED trigger guarantees that the combined PWR and ACT
LED is on for at least half of every second. Under heavy SD card
load it emits a steady 1Hz square wave.

Make the combined mmc0 activity & power trigger available to use.

Signed-off-by: Phil Elwell <phil@raspberrypi.com>

The actpwr trigger is a meta trigger that cycles between an inverted
mmc0 and default-on. It is written in a way that could fairly easily
be generalised to support alternative sets of source triggers.
