Subject: pinctrl: iproc: Fix iProc and NSP GPIO support
From: Ray Jui <ray.jui@xxxxxxxxxxxx>
commit 091c531b09c151c2d712a8f347009ca3698a2467 upstream.
Since commit 44a7185c2ae6 ("of/platform: Add common method to populate
default bus"), ARM64 platform devices are populated at the
arch_initcall_sync level; as a result, the platform_driver_probe calls
in both the iProc and NSP GPIO drivers fail with -ENODEV since by that
time the platform device was not yet registered.
Replace platform_driver_probe with platform_driver_register, that allow
the device to be register later
Fixes: 44a7185c2ae6 ("of/platform: Add common method to populate default bus")
