Wei Chen 8ab9eada22 fbdev: intelfb: Fix potential divide by zero 
[ Upstream commit d823685486 ]

Variable var->pixclock is controlled by user and can be assigned
to zero. Without proper check, divide by zero would occur in
intelfbhw_validate_mode and intelfbhw_mode_to_hw.

Error out if var->pixclock is zero.
