[Sound-open-firmware] [PATCH] timer: fix external timer doesn't work issue for APL/CNL

[Keyon Jie]

On some platforms(e.g. APL, CNL), the external timer(wall clock)
uses the external interrupt bits, here change the common timer
logic to call interrupt APIs, which give a chance to handle for
different cases.
