V4L/DVB (5947): Adding support for the MT2131 tuner.
This adds support for the Microtune MT2131 tuner. 8VSB mode has been tested but QAM support will likely require more register work. Hauppauge have not announced any QAM devices using the MT2131 so QAM remains undone. For legal reasons, Microtune allowed us to write a GPL driver providing we did not document in significant detail any of the registers. This explains the lack of comments or defined on register names. Signed-off-by: Steven Toth <stoth@hauppauge.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
