Thanks Felipe Balbi and Greg KH. I'm really sorry that I forgot to
add changelog.

no changelog = no commit, sorry. Why do you want to dump GUCTL1?
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.
