Deng Qingfang c2bcdabf2a ramips: fix support for MX25L25635F flash
Patch picked from commit 82618062cf

This enables 4B opcodes for MX25L25635F, to fix the reboot crash
issue (FS#1120) At least 3 devices are using this flash
- GeHua GHL-R-001
- Youku YK1
- Newifi D1

Now the MX25L25635F can be correctly detected without breaking MX25L25635E
