There are three couple (hcnt/lcnt) of registers for each
speed (SS/FS/HS). The driver needs to set the proper couple
of regs according to what speed we are setting.

designware_i2c: Added s/w generation of stop bit

In the newer versions of designware i2c IP there is the possibility
of configuring it with IC_EMPTYFIFO_HOLD_MASTER_EN=1, which basically
requires the s/w to generate the stop bit condition directly, as
the h/w will not automatically generate it when TX_FIFO is empty.

To avoid generation of an extra 0x0 byte sent as data, the
IC_STOP command must be sent along with the last IC_CMD.

This patch always writes bit[9] of ic_data_cmd even in the
older versions, assuming that it is a noop there.

i2c: designware_i2c.c: Add support for the "i2c probe" command

i2c_probe() is changed to reinit the i2c bus upon read failure.
This is naturally the case upon i2c bus probing.

Also, some printf messages upon read failure are removed. As they
would interfere with the "i2c probe" command.

Additionally, i2c_set_bus_speed() now returns 0, so that the
"i2c speed" command can be used.

i2c: Add support for designware i2c controller

Earlier, a driver exists in the u-boot source for designware i2c interface. That
driver was specific to spear platforms. This patch implements the i2c controller
as a generic driver which can be used by multiple platforms

The driver files are now renamed to designware_i2c.c and designware_i2c.h and
these are moved into drivers/i2c folder for reusability by other
platforms
