drm/i915: Adjust BXT HDMI port clock limits
Since
commit e62925567c7926e78bc8ca976cde5c28ea265a49
Author: Vandana Kannan <vandana.kannan@intel.com>
Date: Wed Jul 1 17:02:57 2015 +0530
drm/i915/bxt: BUNs related to port PLL
BXT DPLL can now generate frequencies in the 216-223 MHz range.
Adjust the HDMI port clock checks to account for the reduced range
of invalid frequencies.
