SubjectRe: [PATCH] clk: imx6q: Do not reparent unregistered IMX6QDL_CLK_PERIPH2

Ignore this patch. I'll send a patchset which has another fix for
another case like this one (plus the fix for the typo).

The patchset is actually switching all the imx6 and imx7 clocks
to clk_hw based API, but will include all the necessary fixes
for that to work.
