[media] mn88473: add DVB-T2 PLP support
Adds PLP ID filtering for DVB-T2. It is untested as I don't have any signal having PLP ID other than 0. There is only 2 extra registers, 0x32 and 0x36 on bank2, that are programmed for DVB-T2 but not for DVB-T and all the rest are programmed similarly - so it is likely PLP. Pridvorov reported successfully testing it in Russia with m-PLP streams, on both Vladivostok and Moskow. Tested-by: "Придворов Андрей (Pridvorov Andrey)" <ua0lnj@bk.ru> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
