base: genlock: Use a signed long for the result from wait_timeout

interruptible_wait_timeout returns a signed long, so make sure that
we use a signed long to hold the result. Using an unsigned value would
horribly misinterpet an error such as -ERESTARTSYS.

msm_fb: Allow panels to specify a second mode

This allows for panels that support more than one mode
to specify the maximum configuration. The framebuffer
size is now based on the larger of the primary and
alternate modes.  The alternate mode is also used to
check parameters when userspace is requesting a change
to the framebuffer configuration.

msm_fb: Fix error in y-offset check logic in FB driver

After 4 KB alignment changes, the frame from 3rd buffer doesn't
get updated since during PUT_VSCREEN_INFO ioctl, the driver
returns -1 to userspace due to error in logic because the hole
size is not considered in calculating the logic for validity of
the y-offset. Change fixes this error.

msm_fb: Make buffers aligned to 4K page boundary

This change makes the frame buffers aligned to the page
boundary. Improves GPU performance since accessing the
frame buffer from page boundary is faster.

msm_fb: display: disable pan display and memory access to fb1 and fb2

The native fb1 and fb2 framebuffer memory is not used and not
allocated on the board file. So on the driver side, pan display ioctl
or other operations on fb1 or fb2 framebuffer memory is checked and
invalidated.
