arm: pxa: fix 2nd flash chip address on LP-8x4x

Initial configuration has worng address of the second chip.
There is an alias for the 1st chip at 0x02000000 in earlier
verions of LP-8x4x, so the boot normally.

However, new LP-8x4xs have a bigger 1st flash chip, and hang on
boot without this patch.
