V4L/DVB (13051): DiB7000P: improve rebostness of HAS_LOCK indicator

Browse Source 
Update the dib7000p:
The status is HAS_LOCK only if the demod is able to decode the TPS. Sometimes, there is a TPS data lock, even if the demod is not able to decode it (ex: no RF signal).
For the STK7770P: correct value for the charge pump
