[PATCH v2 2/9] dt-bindings: mmc: sprd: Add another optional clock documentation

From: Baolin Wang
Date: Tue Jun 04 2019 - 04:18:51 EST

For some Spreadtrum platforms like SC9860 platform, we should enable another
gate clock '2x_enable' to make the SD host controller work well. Thus add
documentation for this optional clock.
