x86: Update the io.h file to use {out|in}_{be|le}X macros

Browse source 
The commit 3f70a6f577 ("x86: Add clr/setbits functions")
introduced the {read|write}_ macros to manipulate data.

Those macros are not used by any code in the u-boot project (despite the
io.h itself). Other architectures use io.h with {in|out}_* macros.

This commit brings some unification across u-boot supported architectures.
