u-boot-samsung-i9100: New package (MR 1154)

This is the downstream u-boot port for the Galaxy S2.

The load script has been slightly altered to load the kernel from the
KERNEL partition at the 512 KiB offset, instead of loading it from the
RECOVERY partition, since PostmarketOS places the second initramfs in
the RECOVERY partition.
