From: Stephen Boyd <sboyd@xxxxxxxxxxxxxx>
Some clocks are simple enough that determining if they are
enabled or disabled can be done by reading the 'count' member of
struct clk. Implement support for such clocks in clock-debug.c so
that these types of clocks don't need to implement the
is_enabled() ops.
