__raw_readl is not a replacement for real accessors like
ioread32 or in_be32, because it does not synchronize with the
instruction stream.

The best solution would be if you could find a way to set
the hardware into little-endian mode on all architectures.
From the description, it sounds like the hardware should allow that.
