The current approach of using uclass_get_device() is error-prone. Another

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 function which produces a flags word from a few common PIN_CONFIG

There is sort-of race condition when a pinctrl device is probed. The pinctrl
function is called which may end up using the same device as is being
probed. This results in operations being used before the device is actually
probed.

For now, disallow pinctrl operations on pinctrl devices while probing. An
alternative solution would be to move the operation to later in the
device_probe() function (for pinctrl devices only) but this needs more
thought.

This commit intends to implement "fixed-clock" as in Linux.

If you need a very simple clock to just provide fixed clock rate
like a crystal oscillator, you do not have to write a new driver.
