mtd: rawnand: kioxia: Add support for TH58NVG3S0HBAI4 



Add timings for Kioxia/Toshiba TH58NVG3S0HBAI4. Timings
for this memory matches the timings selected for
TH58NVG2S3HBAI4.

This patch increases eraseblock write speed from 5248 KiB/s
to 6864 KiB/s and erase block read speed from 8542 KiB/s
to 18360 KiB/s

Tested on i.MX6SX.
