mtd: nand: raw: rockchip_nfc: add NAND_SKIP_BBTSCAN option

Browse source 
On Rockchip SoCs the first boot stages are written on NAND
with help of manufacturer software that uses a different format
then the MTD framework. Skip the automatic BBT scan with the
NAND_SKIP_BBTSCAN option to be able to pass the driver probe
function and to let the original data unchanged.
