commit d24cfee7f63d6b44d45a67c5662bd1cc48e8b3ca upstream.
When probing spi device take care of deferred probe of ACPI irq gpio similar like for OF/DT case.
From practical standpoint this fixes issue with vsc-tp driver on
Dell XP 9340 laptop, which try to request interrupt with spi->irq equal to -EPROBE_DEFER and fail to probe with the following error:
vsc-tp spi-INTC10D0:00: probe with driver vsc-tp failed with error -22
