board/orangepi-pc-plus: switch to GPT partitions for PARTLABEL support
In new kernels sunxi-mmc driver has been switched to asynchronous probe. As a result, mmc (SD/eMMC) indexes can be shuffled breaking board boot. Switch to GPT partitions to use partition labels instead of explicit mmcblk device names. Note that the default GPT partition table location conflicts with the SPL location, so move GPT table after bootloaders.
