drm/i915/bxt: Reject DMC firmware versions with known bugs

Browse source

DMC version 1.06 has a known bug, where the firmware polls forever for a
port PLL to lock, if the PLL was disabled when entering DC5, which locks
up the machine. Version 1.07 fixes this, so make that the minimum
required version on BXT.
