Current cmdlinepart.c uses offset value 0 to specify a continuous
partition. This prevents creating a second partition starting at 0.
For example, I can split 4MB device using "mtdparts=id:2M,2M", but I
can not do "mtdparts=id:2M@2M,2M@0" to swap mtd0 and mtd1.
This patch introduces special OFFSET_CONTINUOUS value for a continuous
partition and allows 0 for offset value.
Also this patch replaces 0xffffffff with ULONG_MAX for SIZE_REMAINING.
