Rework RAM disk driver to be configured using devicetree and
support multiple instances.
This patch also removes a copy of the RAM disk driver,
tests/subsys/fs/fat_fs_dual_drive/src/disk_access_test_drv.c,
that was there for testing multiple disk drivers support.
Bonus: one SYS_INIT() less and a memory region can be exported to the
host.

the PCIe bus, so let's add this case here to verify that the newly added
NVMe controller and disk driver works fine.
