[PATCH 1/2] ARM: dts: broadcom: bcm2835-rpi: Move the firmware node down 1 level

["Rob Herring (Arm)" <robh@kernel.org>]

Commit 32eea985999b ("ARM: dts: broadcom: bcm2835-rpi: Move non
simple-bus nodes to root level") moved the firmware nodes into the
standard /firmware. However, /firmware is intended to be just a
container for firmware nodes as it is possible to have multiple types of
firmware (e.g. SCMI, OP-TEE, etc.). Move the RPi firmware down a level.

Fixes: 32eea985999b ("ARM: dts: broadcom: bcm2835-rpi: Move non simple-bus nodes to root level")
Reported-by: Marek Szyprowski <m.szyprowski@samsung.com>

This is only half the fix. Unfortunately, a kernel change[1] is also 
needed to make this all work. I do plan for that to go to stable. I'll 
leave it up to the Broadcom maintainers whether it's preferred to revert 
the fixed patches or apply these fixes. A 3rd option is revert for now 
and apply these DT changes some time later to give some time for stable 
updates.
