haswell: bring down EC_EDP_VDD_EN with PP330_DX
The display rail is generated from the PP3300_DX rail, but it
is enabled by the EC_EDP_VDD_EN signal. Therefore, bring down
the EC_EDP_VDD_EN signal before bringing down the PP330_DX
rail. Additionally, always set the EC_EDP_VDD_EN signal based
on the PCH_EDP_VDD_EN in the x86 power interrupt. The reasoning
is so the signal doesn't indavertently remained set.
