[PATCH 3/3] mips: ingenic: Do not manually reference the CPU clock

[Aidan MacDonald <aidanmacdonald.0x0@gmail.com>]

It isn't necessary to manually walk the device tree and enable
the CPU clock anymore. The CPU and other necessary clocks are
now flagged as critical in the clock driver, which accomplishes
the same thing in a more declarative fashion.
