[RFC PATCH v3 1/1] mtd: rawnand: mtk: Re-license MTK NAND driver as Dual MIT/GPL

[Xiaolei Li <xiaolei.li@xxxxxxxxxxxx>]

It is allowed to use MTK NAND driver with GPL-2.0 or MIT license.
But now it is only licensed as GPL-2.0.
So re-license it as dual MIT/GPL and replace license text with
SPDX tag.
