These drivers cannot necessarily be converted to use the clock framework. If the codec is on a I2C/SPI bus, a nested clk_get would be needed to enable the bus clock. But the clock framework does not support nested operations and this would deadlock. So it isn't possible to implement I2C/SPI connected pll/clock hardware through the clock framework. This patch adds new dt properties that list phandles of components with the pll/sysclk settings to be applied. Multiple settings can be given for the same phandle to allow for components with multiple clocks and plls. The plls and sysclks are enabled when the card bia level moves to STANDBY and disabled when it moved to OFF. As this is a _simple_ machine driver, the code does not attempt to handle specifying complex clock ordering interdependencies between components. The plls and sysclks are applied to a component as it is passed to the card set_bias_level/set_bias_level_post callbacks. It follows from this that the order components are configured is the order that they are passed to those callbacks.

Configurations are provided for Cirrus Logic codecs CS42L92, CS47L15, CS47L24, CS47L35, CS47L90 and WM8998. For each codec there is a sound node and a codec device node and both default to disabled. Enable the pair for the codec in use.
