--- Comment #6 from James Ausmus <james.ausmus at intel.com> ---
Issue was that we were not masking out the previous value for the PLL to DDI
mapping before OR'ing in the new value. Thus, with HDMI/DP previously being
mapped to DPLL1, when we tried to map it to DPLL0, the register continnued to
contain the mapping to DPLL1, which was disabled.
