drivers/rtc/rtc-pl031.c uses __raw_readl()?

Reading the macro definitions I come to the conclusion that readl()
is always little-endian and __raw_readl() is the machine endianness,
so that if you put your ARM in BE mode or synthesize this PrimeCell
on PPC, it will not work. PrimeCell registers are always LE I believe.

Now none of that was exactly obvious so please correct me if I'm
wrong!

I sent a patch you can slam on.
