[PATCH u-boot 4/4] board: purism: Use U-Boot mmc function for converting boot part to part access

["Pali Rohár" <pali@kernel.org>]

eMMC Boot Partition Enable bits in mmc->part_config (EXT_CSD[179]) has
different coding than eMMC Partition Access bits.

Use spl_mmc_emmc_boot_partition() function which does this conversion
properly (hopefully).
