[PATCH u-boot] mmc: Use EXT_CSD_EXTRACT_BOOT_PART() macro for extracting boot part

[Pali Rohár]

Mask macro PART_ACCESS_MASK filter out access bits of emmc register and
macro EXT_CSD_EXTRACT_BOOT_PART() extracts boot part bits of emmc register.
So use EXT_CSD_EXTRACT_BOOT_PART() when extracting boot partition.
