[PATCH v9 0/2] clk: Add functions to get optional clocks

[Phil Edworthy <phil.edworthy@renesas.com>]

Quite a few drivers get an optional clock, e.g. a bus clock required to 
access peripheral's registers that is always enabled on some devices.

v9:
 - Add a separate patch to add a comment about __of_clk_get_by_name() error
   values.
 - Add brackets after devm_clk_get so people know it's a function.
 - Add kernel doc for clk_get_optional().
