media: staging/intel-ipu3-v4l: reduce kernel stack usage
The v4l2_pix_format_mplane structure is too large to be put on the kernel
stack, as we can see in 32-bit builds:
drivers/staging/media/ipu3/ipu3-v4l2.c: In function 'imgu_fmt':
drivers/staging/media/ipu3/ipu3-v4l2.c:753:1: error: the frame size of 1028 bytes is larger than 1024 bytes [-Werror=frame-larger-than=]
By dynamically allocating this array, the stack usage goes down to an
acceptable 272 bytes for the same x86-32 configuration.
Fixes: a0ca1627b450 ("media: staging/intel-ipu3: Add v4l2 driver based on media framework")
