This fixes an issue with OpenBSD's bootloader, and I think should also
fix a similar issue with grub2 on legacy devices. In the legacy case
we were creating disk objects for the partitions, but not also the
parent device.

When searching for partitions don't stop if a partition is not present
for a given partition number as there may be valid partitions after.
Search for up to MAX_SEARCH_PARTITIONS matching the other callers of
part_get_info().
This allows OpenBSD to boot via the efi_loader on rpi_3 again after
changes made after U-Boot 2017.09. With MBR partitioning OpenBSD will
by default use the fourth partition for the 0xA6 (OpenBSD) partition.

Correct a mistake in the part number handling of
16a73b249d138fedeb188710533902ed7aac1ddc and only increment part once
per loop.
