i2c: mv64xxx: Fix timing issue on Armada XP (errata FE-8471889)
All the Armada XP (mv78230, mv78260 and mv78460) have a silicon issue in the I2C controller which violate the i2c repeated start timing. The I2C standard requires a minimum of 4.7us for the repeated start condition whereas the I2C controller of the Armada XP this time is 2.9us. So this patch adds a 5us delay for the start case only if the the compatible i2c-mv78230 is set.
