soc/mediatek/mt8195: Skip PCIe ops for eMMC SKUs 

To avoid unnecessary PCIe early initialization for non-NVMe devices
(which would take about 150ms on dojo), skip setting PCIe ops when
initializing mt8195 SoC.

BUG=b:238850212
TEST=emerge-cherry coreboot
TEST=Dojo SKU1 (eMMC) boot time <= 1s
BRANCH=cherry
