media: cx23885: add simple suspend/resume
After suspend-to-memory or suspend-to-disk, additional chips are no longer
reachable via i2c. Trying to tune to DVB-C on a cx23885 based
Hauppauge WinTV-HVR-4400-HD:
si2165 8-0064: could not set chip_mode
tda18271: performing RF tracking filter calibration
This patch implements the simplest possible suspend/resume that is
enough to tune to dvb-c channel after resume.
Afterwards dmesg looks like this:
