[U-Boot] [PATCH 2/2] MIPS: convert IO port accessor functions to 'static inline'

[Gabor Juhos]

The currently used 'extern inline' directive causes
the following compiler warnings if CONFIG_SWAP_IO_SPACE
is defined:

  <...>/include/asm/io.h:345:1: warning: '__fswab32' is static but used in inline function '__outlc_p' which is not static [enabled by default]
  <...>/include/asm/io.h:345:1: warning: '__fswab32' is static but used in inline function '__outl_p' which is not static [enabled by default]

NOTE: checkpatch.pl throwns some errors/warnings for the patch:

However those errors are already present if the
'arch/mips/include/asm/io.h' file is checked
with checkpatch.pl. The cleanup should be done
in a separare patch.
