media: imx-jpeg: Ensure power suppliers be suspended before detach them
commit fd0af4cd35da0eb550ef682b71cda70a4e36f6b9 upstream.
The power suppliers are always requested to suspend asynchronously, dev_pm_domain_detach() requires the caller to ensure proper synchronization of this function with power management callbacks. otherwise the detach may led to kernel panic, like below:

media: imx-mipi-csis: Drop extra clock enable at probe()
[ Upstream commit fb387fcb5cdd0384ba04a5d15a3605e2dccdab2a ]
The driver always enables the clocks at probe() and disables them only at remove(). It is not clear why the driver does this, as it supports runtime PM, and enables and disables the clocks in the runtime resume and suspend callbacks. Also, in the case runtime PM is not available, the driver calls the resume and suspend callbacks manually from probe() and remove().
Drop the unnecessary clock enable, thus enabling the clocks only when actually needed.

media: imx: imx7-media-csi: Fix applying format constraints
v4l_bound_align_image() aligns to a multiple of 2 to the power of walign, not to walign. Depending on the pixel format, this causes the image width to be aligned to 16 or 256 pixels instead of 4 or 8 as required by the hardware. Fix it by rounding and clamping the width and height manually.
