Move the function description comment to immediately above the
function implementation, the add function parameter descriptions to
prevent kernel-doc warnings:

clk-usb.c:80: warning: expecting prototype for sunxi_usb_clk_setup(). Prototype was for SUNXI_USB_MAX_SIZE() instead
clk-usb.c:91: warning: Function parameter or struct member 'node' not described in 'sunxi_usb_clk_setup'
clk-usb.c:91: warning: Function parameter or struct member 'data' not described in 'sunxi_usb_clk_setup'
clk-usb.c:91: warning: Function parameter or struct member 'lock' not described in 'sunxi_usb_clk_setup'
