Hello

This patchset adds a new set of functions which are open-coded in lot of
place.
Basicly the pattern is always the same, "read, modify a bit, write"
some driver already have thoses pattern them as functions. (like ahci_sunxi.c or dwmac-meson8b)

The first patch rename some powerpc funtions which already use the same name (xxxbits32)
but with only bigendian values.

The second patch adds the header.
The third patch is an ugly try to implement a coccinelle semantic patch to
find all place where xxxbits function could be used.
Probably this spatch could be better written and I didnt found an easy way to add the "linux/setbits" header.

The two last patch are example of convertion of two drivers.
Thoses patchs give an example of the reduction of code won by using xxxbits32.

This patchset is tested with the ahci_sunxi and dwmac-sun8i drivers.

Regards

  powerpc: rename setbits32/clrbits32 to setbits32_be/clrbits32_be
  include: add
    setbits32/clrbits32/clrsetbits32/setbits64/clrbits64/clrsetbits64 in
    linux/setbits.h
  coccinelle: add xxxsetbitsXX converting spatch
  net: ethernet: stmmac: use xxxsetbits32
  ata: ahci_sunxi: use xxxsetbits32 functions
