Change all clrsetbits_leXX() to clrsetbitsXX() This patch changes all existing instances of clrsetbits_leXX() to the new endian-independent clrsetbitsXX(), after double-checking that they're all in SoC-specific code operating on CPU registers and not actually trying to make an endian conversion. This patch was created by running sed -i -e 's/\([cs][le][rt]bits\)_le\([136][624]\)/\1\2/g' across the codebase and cleaning up formatting a bit.
