GUCTL1 reg has some useful functions which can be
written by user. For rockchip platform, we set
GUCTL1.DEV_FORCE_20_CLK_FOR_30_CLK (bit26, applicable
for the core is programmed to operate in 2.0 device
only) to 1 in bootrom, and after start the kernel,
we want to check whether this bit can be reset to
default 0 after the core reset. Dump GUCTL1 reg from
debugfs is more convenient for us.

We can't take patches with no changelog text at all, sorry.

Please explain why you are doing what you are doing in the changelog
text.

     Because GUCTL1 can be written by user. For rockchip platform,
     we set GUCTL1.DEV_FORCE_20_CLK_FOR_30_CLK(bit26) to 1 in 
bootrom(used for usb2.0 device only),
     and after kernel boot, I want to check whether this bit can be 
reset to default 0 after core reset.
     Dump GUCTL1 reg from debugfs is more convenient for me.
