soc/intel/common/block: Use pci_dev_request_bus_master for BM enabling

Enabling Bus Master isn't required by the hardware, so we shouldn't need
to enable it at all. However, some payloads do not set this bit before
attempting DMA transfers, which results in boot failures.

Replace static sata_final() implementation for BM enabling with generic
pci_dev_request_bus_master() function.

This allows the user to control through Kconfig whether Bus Master
should be enabled.

TEST=Able to boot to OS from SATA device on CML platform.
