clk: qcom: Return error pointers for unimplemented clocks

Browse Source 
Not all clocks are implemented but client drivers can still
request them. Currently we will return a NULL pointer to them if
the clock isn't implemented in software but NULL pointers are
valid clock pointers. Return an error pointer so that driver's
don't proceed without a clock they may actually need.
