Subject: [PATCH 1/4] staging: media: zoran: add logging macros

This adds the zrdev_dbg() (pointing to pci_dbg()), zrdev_err() (pointing
to pci_err()), and zrdev_info() (pointing to pci_info()) macros to the
zoran drivers. These are the preferred method for debugging and this
will allow to extract the device from the zoran struct to make the call.
