V4L/DVB (8807): Add DVB support for the Leadtek Winfast PxDVR3200 H

Browse Source 
This patch is on behalf of Stephen Backway <stev391@email.com>, and
represents two patches I received (and some subsequent whitespace
cleanup I had due to how I pulled the patches).

From the original author:

a) Add DVB support for the Leadtek Winfast PxDVR3200 H.

b) The tuner callback previously checked the command 3 times:
1) To see if it was the XC2028_RESET_CLK
2) To see if it was not the XC2028_RESET_TUNER
3) To see if it was the XC2028_RESET_TUNER
This patch removes the third check.
