[PATCH 3.16 40/63] video: fbdev: Set pixclock = 0 in goldfishfb

[Ben Hutchings]

3.16.81-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Christoffer Dall <christoffer.dall@xxxxxxxxxx>

commit ace6033ec5c356615eaa3582fb1946e9eaff6662 upstream.

User space Android code identifies pixclock == 0 as a sign for emulation
and will set the frame rate to 60 fps when reading this value, which is
the desired outcome.
