target/ppc: Use proper logging function for possible guest errors
fprintf() and qemu_log_separate() are frowned upon these days for printing logging information in QEMU. Accessing the wrong SPRs indicates wrong guest behaviour in most cases, and we've got a proper way to log such situations, which is the qemu_log_mask(LOG_GUEST_ERROR, ...) function. So use this function now for logging the bad SPR accesses instead.
