In function probe(), it returns directly without unregistered hws
when error occurs.
Fix this by adding 'goto unregister_hws;' on line 295 and
line 310.
Use devm_kzalloc() instead of kzalloc() to automatically
free the memory using devm_kfree() when error occurs.
Replace of_iomap() with devm_of_iomap() to automatically
handle the unused ioremap region and delete 'iounmap(anatop_base);'
in unregister_hws.

The variable “base” was passed to a call of the function “PTR_ERR”
in the implementation of the function “imx93_clocks_probe”.
Unfortunately, the variable was not assigned to an error pointer
before this if branch.
Thus use the variable “anatop_base” for an error code assignment instead.
