With MFD devices the clk properties may be contained in MFD (parent) DT
node. Current devm_of_clk_add_hw_provider assumes the clk is bound to MFD
subdevice not to MFD device (parent). Add
devm_of_clk_add_hw_provider_parent to tackle this issue.

Also clkdev registration lacks of managed registration functions and it
seems few drivers do not drop clkdev lookups at exit. Add
devm_clk_hw_register_clkdev and devm_clk_release_clkdev to ease lookup
releasing at exit.
Please split this into clkdev and non-clkdev devm functionality.
Allright. I'll split this to two patches.
Definitely, please note that clkdev is separate from the common
clk stuff, and is actually maintained by a different person (me)
although I currently defer much of the review to the common clk
guys.
