If an error occurs after a successful pm_genpd_init() call, it should be
undone by a corresponding pm_genpd_remove().
Add the missing call in the error handling path, as already done in the
remove function.
Fixes: bf6910abf548 ("power: avs: Add support for CPR (Core Power Reduction)")

do_div() does a 64-by-32 division. Here the divisor is an unsigned long
which on some platforms is 64 bit wide. So use div64_ul instead of do_div
to avoid a possible truncation.

devm_platform_ioremap_resource()
Use the devm_platform_ioremap_resource() helper instead of
calling platform_get_resource() and devm_ioremap_resource()
separately

Let's delete the private function cpr_read_efuse() since it does the
basically the same thing as the new API call
nvmem_cell_read_variable_le_u32().
Differences between the new API call and the old private function:
* less error printing (I assume this is OK).
* will give an error if the value doesn't fit in 32-bits (the old code
would have truncated silently).

The avs drivers are all SoC specific drivers that doesn't share any code.
Instead they are located in a directory, mostly to keep similar
functionality together. From a maintenance point of view, it makes better
sense to collect SoC specific drivers like these, into the SoC specific
directories.
Therefore, let's move the qcom-cpr driver to the qcom directory.
