Christophe Leroy 894fa235eb powerpc: inline iomap accessors 
ioreadXX()/ioreadXXbe() accessors are equivalent to ppc
in_leXX()/in_be16() accessors but they are not inlined.

Since commit 0eb5736828 ("powerpc/kerenl: Enable EEH for IO
accessors"), the 'le' versions are equivalent to the ones
defined in asm-generic/io.h, allthough the ones there are inlined.

Include asm-generic/io.h to get them. Keep ppc versions of the
'be' ones as they are optimised, but make them inline in ppc io.h.

This reduces the size of ppc64e_defconfig build by 3 kbytes:

   text	   data	    bss	    dec	    hex	filename
10160733	4343422	 562972	15067127	 e5e7f7	vmlinux.before
10159239	4341590	 562972	15063801	 e5daf9	vmlinux.after

A typical function using ioread and iowrite before the change:
