media: tvp5150: split reset/enable routine
To trigger standard autodetection only the reset part of the routine
is necessary during probe(). Split this out to make it callable on its own.
[m.felsch@pengutronix.de: adapt commit message]
[m.felsch@pengutronix.de: add tvp5150_enable() to tvp5150_s_stream()]
[m.chehab@samsung.com: fix a compilation breakage]
