P4080/mtd: Fix the freescale lbc issue with 36bit mode

Browse source 
When system uses 36bit physical address, res.start is 36bit
physical address. But the function of in_be32 returns 32bit
physical address. Then both of them compared each other is
wrong. So by converting the address of res.start into
the right format fixes this issue.
