If the ACPI tables change as a result of a dinamically loaded table
and a bus rescan is required the enumeration/visited flag are not
consistent.

I2C/SPI are not directly enumerated in acpi_bus_attach(), however
the visited flag is set. This makes it impossible to check if an
ACPI device has already been enumerated by the I2C and SPI
subsystems. To fix this issue we only set the visited flags if
the device is not I2C or SPI.

With this change we also need to remove setting visited to false
from acpi_bus_attach(), otherwise if we rescan already enumerated
I2C/SPI devices we try to re-enumerate them.

Note that I2C/SPI devices can be enumerated either via a scan handler
(when using PRP0001) or via regular device_attach(). In either case
the flow goes through acpi_default_enumeration() which makes it the
ideal place to mark the ACPI device as enumerated.
