Fix boot1 and loader on PowerPC64 little-endian (LE). Due to endian issues, boot1 couldn't find the UFS boot partition and loader wasn't able to load the kernel. Most of the issues happened because boot1 and loader were BE binaries trying to access LE UFS partitions and because loader expects the kernel ELF image to use the same endian as itself. To fix these issues, boot1 and loader are now built as LE binaries on PPC64LE. To support this, the functions that call OpenFirmware were enhanced to correctly perform endian conversion on its input and output arguments and to change the CPU into BE mode before making the calls, as OpenFirmware always runs in BE. Besides that, some other small fixes were needed.
