nand: mxc: Switch NAND SPL to generic SPL
This also fixes support for mx31pdk and tx25, which had been broken by commit e05e5de7fae5bec79617e113916dac6631251156. Signed-off-by: Benoît Thébaudeau <benoit.thebaudeau@advansee.com> Acked-by: Scott Wood <scottwood@freescale.com> Tested-by: Fabio Estevam <fabio.estevam@freescale.com>
