[PATCH 5.10.y] of: platform: Use default match table for /firmware

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

Calling of_platform_populate() without a match table will only populate
the immediate child nodes under /firmware. This is usually fine, but in
the case of something like a "simple-mfd" node such as
"raspberrypi,bcm2835-firmware", those child nodes will not be populated.
And subsequent calls won't work either because the /firmware node is
marked as processed already.

Switch the call to of_platform_default_populate() to solve this problem.
It should be a nop for existing cases.
