asm-generic/io.h: convert readX defines to functions
E.g. readl is defined like this
#define readl(addr) __le32_to_cpu(__raw_readl(addr))
If a there is a readl() call that doesn't check the return value
this will cause a compile warning on big endian machines due to
the __le32_to_cpu macro magic.
E.g. code like this:
readl(addr);
will generate the following compile warning:
warning: value computed is not used [-Wunused-value]
With this patch we get rid of dozens of compile warnings on s390.
