mmc: sdhci-pci: Fix default d3_retune for Intel host controllers

commit eb701ce16a45ed9880897c48f05ee608d77c72e3 upstream.

The default for d3_retune is true, but that was not being set in all cases,
which results in eMMC errors because re-tuning has not been done.
Fix by initializing d3_retune to true.
