b18490138d PM: AVS: qcom-cpr: Fix an error handling path in cpr_probe() 
[ Upstream commit 6049aae52392539e505bfb8ccbcff3c26f1d2f0b ]

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: bf6910abf5 ("power: avs: Add support for CPR (Core Power Reduction)")

81d2e96aba PM: AVS: qcom-cpr: Use div64_ul instead of do_div 
[ Upstream commit 92c550f9ffd2884bb5def52b5c0485a35e452784 ]

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.

a7305e684f PM: AVS: qcom-cpr: Move the driver to the qcom specific drivers 
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.
