atmel_lcdfb: avoid division by zero
Avoid division by zero in atmel_lcdfb_check_var() function.
If pixclock is not specified while passing a var structure in
the check_var() funtion, a division by zero occurs (when
translating pixclock to KHz).
This patch adds a checking of this value and try to choose a
video mode in the modelist.
The mode found in the probe function in added to the modelist.
