clk: sunxi-ng: Prevent unbinding CCUs via sysfs
The CCU drivers are not really designed to be unbound. Unbinding a SoC's
main CCU is especially pointless, as very few of the peripherals on the
SoC will work without it. Let's avoid any potential problems by removing
the bind/unbind attributes from sysfs for these drivers.
This change is not applied to the "secondary" CCUs (DE, USB) as those
could reasonably be unbound without making the system useless.
