Pull clk fixes from Stephen Boyd:
"Mostly driver fixes, but there's a core framework fix in here too:
- Revert the commits that introduce clk management for the SP clk on
MMP2 SoCs (used for OLPC). Turns out it wasn't a good idea and
there isn't any need to manage this clk, it just causes more
headaches.
- A performance regression that went unnoticed for many years where
we would traverse the entire clk tree looking for a clk by name
when we already have the pointer to said clk that we're looking for
- A parent linkage fix for the qcom SDM845 clk driver
- An i.MX clk driver rate miscalculation fix where order of
operations were messed up
- One error handling fix from the static checkers"
