firmware: meson_sm: populate platform devices from sm device tree data

Browse source 
[ Upstream commit e45f243409 ]

In some meson boards, secure monitor device has children, for example,
power secure controller. By default, secure monitor isn't the bus in terms
of device tree subsystem, so the of_platform initialization code doesn't
populate its device tree data. As a result, secure monitor's children
aren't probed at all.

Run the 'of_platform_populate()' routine manually to resolve such issues.
