Add a feature which speeds up the CPU to full speed in SPL to minimise
boot time. This is only supported for certain boards (at present only
jerry).

Fix a number of small errors which were found in reviewing the clock code.

The displays need to use NPLL and also select some new peripheral clocks.
Add support for these to the clock driver.

These should match the datasheet naming. Adjust them.

The current method assumes that clocks are numbered from 0 and we can
determine a clock by its number. It is safer to use an ID in the clock's
platform data to avoid the situation where another clock is bound before
the one we expect.
Move the existing code into rk3036 since it still works there. Add a new
implementation for rk3288.

We can use the new clk_get_by_index() function to get the correct clock.

The current approach of using uclass_get_device() is error-prone. Another
clock (for example a fixed-clock) may cause it to break. Add a function that
does a proper search.

It is useful to be able to read the rate of a peripheral clock. Add a
handler for that.

The current name is confusing and a bit verbose. Rename it.

At present we use the same peripheral ID for clocks and pinctrl. While this
works it is probably better to use the device tree clock binding ID for
clocks. We can use the clk_get_by_index() function to find this.
Update the clock drivers and the code that uses them.

Add a driver for setting up and modifying the various PLLs and peripheral
clocks on the RK3288.
