zoran: Remove global device array

From: Trent Piepho <xyzzy@speakeasy.org>

The driver was keeping a global array with an entry for each zoran device
probed.  It was a leftover from when the driver didn't dynamically allocate
the driver data for each device.

There was only one use left, in the video device's ->open() method, looking
up the struct zoran for the opened device from the minor number.  This can
be done better with video_get_drvdata().

Since zoran_num is now only used in the pci driver's ->probe() method, it
doesn't need to be an atomic_t and be static.  There is a race if multiple
zoran cards could be probed at the same time, but currently the probe
method for a given driver is single threaded.

Priority: normal
