disk: part_dos: Use the original allocation scheme for the SPL case
Since commit ff98cb90514d ("part: extract MBR signature from partitions")
SPL boot on i.MX6 starts to fail:
U-Boot SPL 2017.09-00221-g0d6ab32 (Oct 02 2017 - 15:13:19)
Trying to boot from MMC1
(keep in loop)
Use the original allocation scheme for the SPL case, so that MX6 boards
can boot again.
This is a temporary solution to avoid the boot regression.
