Have igt_pipe_crc_new() check whether the selected source is actually
supported.

This was a previous attempt to solve the first CRC being bogus. We know
wait for it and discard it at the end of the function.

With PLANE1 and PIPE CRC sources the test will work on all currently
shipping (and planed fwiw) platforms.
Also add all the other new sources for non-ivb/hsw chips.

Let's add a new test that sets a mode, wait for a few vblanks (3) and
then make sure we read 3 identical CRCs.
Some subtests check for various parsing errors.
In the process, improve the debugfs helpers to deal with CRCs.
