Revert "soc: qcom: stats: Add DDR sleep stats"

After recent reports ([1], [2]) of older platforms (particularly 8150 and
7180) breaking after DDR sleep stats introduction, revert the following:

Commit 73380e2573c3 ("soc: qcom: stats: fix 64-bit division")
Commit e84e61bdb97c ("soc: qcom: stats: Add DDR sleep stats")

The feature itself is rather useful for debugging DRAM power management,
however it looks like the shared RPMh stats data structures differ on
previous SoCs.

Revert its addition for now to un-break booting on these earlier SoCs,
while I try to come up with a better way to enable it conditionally.
