media: staging/intel-ipu3: reduce kernel stack usage
The imgu_css_queue structure is too large to be put on the kernel
stack, as we can see in 32-bit builds:
drivers/staging/media/ipu3/ipu3-css.c: In function 'imgu_css_fmt_try':
drivers/staging/media/ipu3/ipu3-css.c:1863:1: error: the frame size of 1172 bytes is larger than 1024 bytes [-Werror=frame-larger-than=]
By dynamically allocating this array, the stack usage goes down to an
acceptable 140 bytes for the same x86-32 configuration.
Fixes: f5f2e4273518 ("media: staging/intel-ipu3: Add css pipeline programming")
