[PATCH 0/4] ARM: imx6q: clean up board specific CLKO setup

[Shawn Guo]

The CLKO is widely used by imx6q board designs to clock audio codec.
Currently, imx6q-sabrelite and imx6qdl-sabresd set up CLKO in board
specific hooks, while imx6qdl-wandboard handles that in U-Boot.
Since most audio codecs accept 24 MHz frequency, the series adds missing
CLKO pieces into clock driver, and initially sets up CLKO with OSC24M
(cko <-- cko2 <-- osc).  Then those board specific CLKO setup for audio
codec can be removed, while it improves the power efficiency at the same
time by saving the use of PLL.
