drm/i915/dp: Extend intel_dp_can_support_m_n() for BMG M/N bypass
On BMG platforms, the standard M/N ratio limit of 10 can be bypassed
under specific conditions, as permitted by hardware capabilities.
Modify the helper intel_dp_can_support_m_n() to account for this by
checking whether the platform supports bypassing the limit.
During mode_valid phase, the check assumes that PIPE_A will be used to
allow the mode, where M/N ratio is with int the limits for the workaround.
