Change in coreboot[master]: device: Rework bus master option

[Felix Singer (Code Review)]

Hello build bot (Jenkins), Nico Huber, Paul Menzel, Angel Pons, Michael Niewöhner,

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/coreboot/+/45149

to look at the new patch set (#4).

Change subject: device: Rework bus master option
......................................................................

device: Rework bus master option

As an intermediate step for CB:45150, add an additional Kconfig option
which is used to configure bus mastering for any devices and use
PCI_ALLOW_BUS_MASTER to allow coreboot setting the bus mastering bit in
general.
