[PATCH] soc: qcom: stats: Fix division issue on 32-bit platforms

[Bjorn Andersson]

commit 'e84e61bdb97c ("soc: qcom: stats: Add DDR sleep stats")' made it
in with a mult_frac() which causes link errors on Arm and PowerPC
builds:

  ERROR: modpost: "__aeabi_uldivmod" [drivers/soc/qcom/qcom_stats.ko] undefined!

Expand the mult_frac() to avoid this problem.
