media: iris: Fix bus_info prefix in VIDIOC_QUERYCAP
The bus_info field returned by VIDIOC_QUERYCAP used the abbreviated
prefix "plat:" instead of the standard "platform:" prefix expected
for platform devices. v4l2-compliance validates that bus_info for
platform devices starts with "platform:", and fails otherwise:
fail: ../utils/v4l2-compliance/v4l2-compliance.cpp(671):
missing bus_info prefix ('plat:aa00000.video-codec:dec')
Update the format string in iris_querycap() to use "platform:" so
that v4l2-compliance bus_info check passes.
Fixes: 94ef75095d5e ("media: iris: Enumerate cap->bus_info to differentiate between encoder and decoder")
