A future patch is going to change semantics of clk_register() so that
clk_hw::init is guaranteed to be NULL after a clk is registered. Avoid
referencing this member here so that we don't run into NULL pointer
exceptions.

Switch over to the more modern style of registering parents and simplify
the code in the process.

Lochnagar is an evaluation and development board for Cirrus
Logic Smart CODEC and Amp devices. It allows the connection of
most Cirrus Logic devices on mini-cards, as well as allowing
connection of various application processor systems to provide a
full evaluation platform. This driver supports the board
controller chip on the Lochnagar board.
The Lochnagar can take several input clocks from the host system,
provides several of its own clock sources, and provides extensive
routing options for those clocks to be supplied to the attached
CODEC/Amp device.
