powerpc: Remove powerpc specific sinf and cosf optimization

New generic optimization of sinf and cosf introduced by commit
599cf3976679e1b345307d9c02057f02aa95528f shows improvement
compared to powerpc specific assembly version.  Hence removing
the powerpc assembly versions to make use of generic code.
