cc_trng_clk_init is called only from the probe function. Merge the two
functions, this saves some lines of code.

Call devm_clk_get_optional_enabled in the cctrng driver. We don't have to
disable and unprepare the clock any more in error paths or in the remove
function.

Do not open code the init and exit functions of the cctrng driver.
If we move the BUILD_BUG_ON checks into the probe function, we can use
module_platform_driver and make the code shorter.

platform_get_irq() has already checked and printed the return value,
the printing here is nothing special, it is not necessary at all.

Common pattern of handling deferred probe can be simplified with
dev_err_probe(). Less code and also it prints the error value.
