mtd: rawnand: toshiba: Choose the interface configuration for TH58NVG2S3HBAI4
The Kioxia/Toshiba TH58NVG2S3HBAI4 NAND memory is not ONFI compliant. The timings of the NAND chip memory are quite close to ONFI mode 4 but is breaking that spec. By providing our own set of timings, erase block read speed is increased from 6910 kiB/s to 13490 kiB/s and erase block write speed is increased from 3350 kiB/s to 4410 kiB/s. Tested on IMX6SX which has a NAND controller supporting EDO mode.
