[media] m88ds3103: implement set voltage and TS clock
Implement set voltage operation. Separate TS clock as a own configuration parameter. Add TS clock polarity parameter. [crope@iki.fi: merge em28xx driver m88ds3103 config change patch to that one, in order to keep build unbroken] Signed-off-by: Nibble Max <nibble.max@gmail.com> Reviewed-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
