ARM: 6406/1: at91sam9g45: fix i2c bus speed
Use a correct udelay value to get bus speed around 100KHz. The udelay
value was most likely copied from the older devices, but the 9g45
is signicantly faster (400MHz, DDR, ..), so a udelay of 2 gives a
bus speed of around 190KHz, which is too fast for some devices.
A udelay value of 5 gives a bus speed of around 90KHz here.
