Reject unsupported pixel formats in rkisp1_enum_framesizes() to
fix v4l2-compliance failure.

v4l2-compliance test failure:

fail: ../utils/v4l2-compliance/v4l2-test-formats.cpp(403): Accepted framesize for invalid format
test VIDIOC_ENUM_FMT/FRAMESIZES/FRAMEINTERVALS: FAIL

Tested on: Debix i.MX8MP Model A
Kernel version: v6.17-rc3
v4l2-compliance: 1.31.0-5387
