drm/i915: Warn if a pipe is enabled with a bogus port
If TRANS_DDI_FUNC_CTL has been wrongly programmed with an incorrect
port, we are currently trying to read PORT_CLK_SEL(port) with an
uninitialized value.
Handle that case by returning PORT_CLK_SEL_NONE and warning about it.
v2: Move the warning inside intel_ddi_get_crtc_pll (Paulo Zanoni)
