This patch replaces the __raw_readl/writel with
readl and writel, Altough the code runs on ARMv5
based SOCs, changing this will help copying the code
for other uses.

This replacement has a functional impact: it adds memory barriers.
Please note this in the description.
Also please add a bit of explanation on why do you need to add barriers.
