my speed is now exactly 68750 so it will remain there.

As exception among the i.MX processors, the i.MX31 has headers
without general names (mx31-regs.h, mx31.h instead of imx-regs.h and
clock.h). This requires several nasty #ifdef in the drivers to
include the correct header. The patch cleans up the driver and
renames the header files as for the other i.MX processors.

I2C: mxc_i2c: address failure with mx35 processor

There is sporadic failures when more as one I2C slave
is on the bus and the processor tries to communicate
with more as one slave.
The problem was seen on a mx35pdk (two I2C slaves,
PMIC controller and CAN/RTC chip).

The current driver uses the IIF bit in the status register
to check if the bus is busy or not. According to the manual,
this is not correct, because the IIB bit should be checked.
Not only, to check if a transfer is finished must be checked
the ICF bit, and this is not tested at all.

This patch comes from analyse with a corresponding driver
provided by Freescale as part of the LTIB tool. Comparing
the two drivers, it appears that the current u-boot driver checks
the wrong bits, and depending on race condition, the transfer
can be successful or not.

The patch gets rid also of own debug function (DPRINTF),
replaced with the general debug().

Tested on Freescale mx35pdk.

i.MX31: Start the I2C clock on driver initialisation

i.MX31 powers on with most clocks running, so, after a power on this explicit
clock start up is not required. However, as Linux boots it disables most clocks
to save power. This includes the I2C clock. If we then soft reboot from Linux
the I2C clock stays off. This breaks the phycore, which has its environment in
I2C EEPROM. Fix the problem by explicitly starting the clock in I2C driver
initialisation routine.
