[PATCH v2 4/4] drm/lima: Reduce the amount of logs on deferred probe of clocks and reset controller

[Krzysztof Kozlowski <krzk@kernel.org>]

There is no point to print deferred probe messages as errors.  Adjust
the printks for error paths of obtaining clocks and reset controller.
This removes the error message of lima_clk_init() call in favor or
specific failure messages inside.
