Applied to nand/next, thanks!

[1/2] mtd: rawnand: esmt: Disable broken timings feature on GD9FU2G8F3A
      commit: e97c701c09d3d8f23397f68478c7e2c7eaf87528
[2/2] mtd: rawnand: Reflect that ESMT and GigaDevice share ID 0xc8
      commit: c62b598ac7f650c963ca00a19f161e99e899498e

Patche(s) should be available on mtd/linux.git and will be
