i2c: designware_i2c: adjust timing calculation
In SPL probing of the designware_i2c device on the StarFive VisionFive 2
board fails with
dw_i2c: mode 0, ic_clk 1000000, speed 100000,
period 10 rise 1 fall 1 tlow 5 thigh 4 spk 0
dw_i2c: bad counts. hcnt = -4 lcnt = 4
device_probe: i2c@12050000 failed to probe -22
When changing the offset for the high phase from 7 to 3 the device is
probed correctly. This now matches the value from the Linux driver.
Without this fix the memory size of the StarFive VisionFive 2 board cannot
be read from EEPROM.
