Running the v4l2-compliance (1.27.0-5208, SHA: af114250d48d) on the m2m
device fails on the MMAP streaming tests, with the following messages:

fail: v4l2-test-buffers.cpp(240): g_field() == V4L2_FIELD_ANY
fail: v4l2-test-buffers.cpp(1508): buf.qbuf(node)

Apparently, the driver does not properly set the field member of
vb2_v4l2_buffer struct, returning the default V4L2_FIELD_ANY value which
is against the guidelines.

Fixes: cf21f328fcafac ("media: nxp: Add i.MX8 ISI driver")

v2:
 * set the 'field' in mxc_isi_video_buffer_prepare() as suggested by
   Laurent;
 * change the commit subject to make it more generic as the fix does
   not address only the M2M device compliance errors but also the
   video capture ones;
