Subject: [PATCH v1] arm64: dts: imx8-ss-img: Avoid gpio0_mipi_csi GPIOs
 being deferred

From: João Paulo Gonçalves <joao.goncalves@...adex.com>

The gpio0_mipi_csi DT nodes are enabled by default, but they are
dependent on the irqsteer_csi nodes, which are not enabled. This causes
the gpio0_mipi_csi GPIOs to be probe deferred. Since these GPIOs can be
used independently of the CSI controller, enable irqsteer_csi by default
too to prevent them from being deferred and to ensure they work out of
the box.

Fixes: 2217f8243714 ("arm64: dts: imx8: add capture controller for i.MX8's img subsystem")
