[MTD] [NAND] nand_base.c: fix type of eccpos pointer
The nand_base.c driver implicitly casts the uint32_t
eccpos array to 'int *', which is not only not guaranteed
to be the same sign as the source, but is not guaranteed
to be the same size.
Fix by changing nand_base.c to use uint32_t
referencing the eccpos fields.
