Move the default eMMC boot partition index used for SPL load to a weak function. So we can override it in iMX8 specified codes. Because on iMX8 when the emmc regular boot is from boot part0/1, ROM will switch to the other boot part for secondary boot. So we can't directly use the boot part index in PARTITION_CONFIG register, but have to check the secondary boot for using correct boot partition.
