Currently, most callers of intel_panel_mode_valid() also call intel_panel_fixed_mode(). This is done either to check for the presence of a fixed mode for the connector or to get the clock of the fixed mode, which is then compared against the max dotclock for the pipe. Since intel_panel_mode_valid() already calls intel_panel_fixed_mode() internally, we can avoid yet another call to intel_panel_fixed_mode() from the caller. Remove the redundant call to intel_panel_fixed_mode() in mode_valid paths. To get the clock for the fixed mode, extend the helper intel_panel_mode_valid() to accept 'target_clock' as an out param. The 'target_clock' can then be used by the callers to check against the max dotclock.
