[PATCH] drm: lima: Add support for multiple reset lines

[PATCH] drm: lima: Add support for multiple reset lines

[John Stultz]

From: Peter Griffin <peter.griffin@linaro.org>

Some SoCs like HiKey have 2 reset lines, so update
to use the devm_reset_control_array_* variant of the
API so that multiple resets can be specified in DT.
