powerpc: Fix operand prefixes
The file sysdeps/powerpc/sysdeps.h defines aliases for condition register operands. E.g.: 'cr7' means condition register 7. On the one hand, this increases readability, as it makes it easier for readers to know whether the operand is a condition register, a general purpose register or an immediate. On the other hand, this permits that condition registers be written as if they were general purpose, and vice-versa, thus reducing the readability of the code. This commit removes some of these unintentional misuses. The changes have no effect on the final code. Checked with objdump.
