Subject: [PATCH 0/2] bus: imx-aipstz: fix probe-related issues

From: Laurentiu Mihalcea <laurentiu.mihalcea@....com>

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.
