From: Cheng Ming Lin <chengminglin@mxic.com.tw>

MX35UF{1,2,4}GE4AD and MX35UF{1,2}GE4AC have been merge into
Linux kernel mainline.
Commit ID: "c374839f9b4475173e536d1eaddff45cb481dbdf".

For SPI-NAND flash support on Linux kernel LTS v5.4.y,
add SPI-NAND flash MX35UF{1,2,4}GE4AD and MX35UF{1,2}GE4AC in id tables.

Those five flashes have been validate on Xilinx zynq-picozed board and
Linux kernel LTS v5.4.y.
