Add pitch length info of graphics/video layer, pitch is used
to represent line length in byte, the usage depends on pix_fmt.
If the fmt is YUV, the pitch[0] will be Y length,pitch[1]
will be U length, pitch[2] will be V lenth.
If the fmt is RGB, the picth[0] will be line lenth, and
pitch[1]/pitch[2] will be 0 and not be used.

The driver core clears the driver data to NULL after device_release
or on probe failure, since commit 0998d0631001288a5974afc0b2a5f568bcdecb4d
(device-core: Ensure drvdata = NULL when no driver is bound).
Thus, it is not needed to manually clear the device driver data to NULL.

Commit 16559ae48c76 ("kgdb: remove #include <linux/serial_8250.h> from
kgdb.h") changes the kgdb.h file so that drivers including it do not
implicitly include linux/platform_device.h. The mmp framebuffer driver
is new, so Greg did not have a chance to fix it up when introducing his
change.
