Isn't it enough to add "no aurtc* at aubus?" to OMSAL400,
or to move "aurtc* at aubus?" declaration from common ALCHEMY
to each board specific config file?

Anyway, "one todr device from multiple RTC devices" should be
selected by each match function or a some priority value
specified by device_register(), rather than strings specified
by kernel config, IMHO.
