V4L/DVB: dib7770: enable the current mirror
To improve performance on DiB7770-devices enabling the current mirror
is needed.
This patch adds an option to the dib7000p-driver to do that and it
creates a separate device-entry in dib0700-device to use those changes
on hardware which is using the DiB7770.
