[PATCH] fbdev: fix the fb_find_nearest_mode() function

Currently the fb_find_nearest_mode() function finds a mode with screen
resolution closest to that described by the 'var' argument and with some
arbitrary refresh rate (eg.  in the following sequence of refresh rates: 70 60
53 85 75, 53 is selected).

This patch fixes the function so that it looks for the closest mode as far as
both resolution and refresh rate are concerned.  The function's first argument
is changed to fb_videomode so that the refresh rate can be specified by the
caller, as fb_var_screeninfo doesn't have any fields that could directly hold
this data.
