Russell King e963408e8f drivers/amba: fix reset control error handling
With commit 79bdcb202a ("ARM: 8906/1: drivers/amba: add reset control
to amba bus probe") it is possible for the the amba bus driver to defer
probing the device for its IDs because the reset driver may be probed
later.

However when a subsequent probe occurs, the call to request_resource()
in the driver returns -EBUSY as the driver has not released the resource
from the initial probe attempt - or cleaned up any of the preceding
actions.

Fix this both for the deferred probe case as well as a failure to get
the reset.
