[PATCH v2] PM / clock_ops: Print acquired clock name in addition to con_id

[Geert Uytterhoeven <geert+renesas@glider.be>]

Currently the con_id of the acquired clock is printed for debugging
purposes.  But in several cases, the con_id is NULL, which doesn't
provide much debugging information when printed.  These cases are:
  - When explicitly passing a NULL con_id (which means the first clock
    tied to the device, if available),
  - When not using pm_clk_add(), but pm_clk_add_clk() (which takes a
    "struct clk *" directly).

Hence print the actual clock name in addition to (and not instead of;
thanks Grygorii Strashko!) the con_id.

Note that the clock name is not available with legacy clock frameworks,
and the hex pointer address will be printed instead.

This is v2 of "PM / clock_ops: Print acquired clock name instead of
con_id".

v2:
  - Print both clock and con_id, as suggested by Grygorii Strashko
    <grygorii.strashko@linaro.org>.
