[PATCH] clk: rockchip: add pclk_cpu to the list of rk3188 critical clocks

Hi Heiko,

I merged yours and mine :-)


pclk_cpu needs to keep running because it is needed for devices like
the act8865 regulator but with the recent gpio clock handling this is
not always the case anymore. So add it to the list of critical clocks.

gpio clock is getting disabled to save power but pclk_cpu is needed for
act8865 regulator
Please refine the commit message a bit :-) . Something along

pclk_cpu needs to keep running and with the recent gpio clock
handling this is not always the case anymore. So add it to the list
of critical clocks.


and also please add "Linus Walleij [off-list ref]" to the list of 
recipients. As the gpio clock handling change does go through his tree, the 
matching critical clock handling should also go through him.
