WIP: soc/mediatek/mt8192: adjust i2c tLOW, tSU,STO
The i2c actiming with the default reg setting cannot meet spec, so we need to set some regs. 1. adjust the ratio of SCL high and low level, to adjust tLOW. 2. modify ext_conf reg to adjust tSU,STO.
BUG=b:179000159 TEST=Test on asurada (MT8192), boot pass, timing pass.
