i2c: mxs: Do not disable the I2C SMBus quick mode

Marek Vasut · Wolfram Sang · commit 8f414059c66f · 2012-11-22T23:03:15.000+01:00
There is no reason to disable the I2C SMBus quick mode on this
IP block. Enable it. This essentially fixes the problem with the
"i2c-detect" command for probing the bus.
