[Intel-gfx] [PATCH 4/4] drm/i915/lspcon: Remove unused force change mode parameter

The reason why I kept the force function was, that during debug phase, I 
saw a need to change LSPCON mode.

Also, in future, if we need to provide an IOCTL/control to userspace, to 
change lspcon mode, force may be required

to differentiate the path from user/kernel space.

But in any case: Reviewed-by: Shashank Sharma <shashank.sharma at intel.com>
