Since the introduction of the i.MX AIPSTZ bridge driver via commit
796cba2dd4d9 ("bus: add driver for IMX AIPSTZ bridge"), a couple of
problems have been reported by Mark Brown and Alexander Stein. Namely:
1) The driver doesn't get compiled when using the ARM64
defconfig [1].
2) The children of the SPBA bus do not get probed [2].
These issues are addressed here by:
1) Enabling the driver config option in the ARM64 defconfig.
2) Replacing devm_of_platform_populate() with
of_platform_populate() and passing a reference to the bus OF
match table to it.
