[POWERPC] add clrsetbits macros
This patch adds the clrsetbits_xxx() macros, which are used to set and clear
multiple bits in a single read-modify-write operation. Specify the bits to
clear in the 'clear' parameter and the bits to set in the 'set' parameter.
These macros can also be used to set a multiple-bit bit pattern using a mask,
by specifying the mask in the 'clear' parameter and the new bit pattern in the
'set' parameter. There are big-endian and little-endian versions for 8, 16,
32, and 64 bits.
