Maintainers need to be notified more directly of the need to convert these

Since busses are sorted in alphabetical order, introducing more
than nine busses led to unexpected behaviour.

In case only the CONFIG_SYS_I2C_SPEED is set in configuration file,
the CONFIG_SYS_I2C_SOFT_SPEED is defined as CONFIG_SYS_I2C_SPEED.
The CONFIG_SYS_I2C_SOFT_SPEED is then used throughout the driver.
Unfortunatelly, due to a typo in the driver, instead of defining
CONFIG_SYS_I2C_SOFT_SPEED, an CONFIG_SYS_SOFT_I2C_SPEED was defined
and therefore the driver failed to compile. The same applies for
CONFIG_SYS_I2C_SOFT_SLAVE , where the swap happens as well.
This patch fixes the issue.

There are some locations in the code which anticipate printf() being called
before the console is ready by squelching printf() on gd->have_console.
Move this squelching into printf(), vprintf(), puts() and putc(). Also
make tstc() and getc() return 0 if console is not yet initialised

Since the vast majority of GPIO I2C implementations behave the same way,
support the common GPIO framework with default settings.
This adds two new defines CONFIG_SOFT_I2C_GPIO_{SCL,SDA} so that boards
which want GPIO I2C support need only define these.

New default, weak i2c_get_bus_speed() and i2c_set_bus_speed() functions
replace a number of architecture-specific implementations.
Also, providing default functions will allow all boards to enable
CONFIG_I2C_CMD_TREE. This was previously not possible since the
tree-form of the i2c command provides the ability to display and modify
the i2c bus speed which requires i2c_[set|get]_bus_speed() to be
present.

This patch adds a #define to optionally change the behaviour of
i2c_read() in soft_i2c.c to send an I2C repeated start instead of a
stop-start between sending the device address pointer write and
reading back the data. The current behaviour is retained as the
default.
While most devices will work either way, I have a smart battery(*)
that requires repeated start, and someone at some point found a
device that required a stop-start.

All implementations of the functions i2c_reg_read() and
i2c_reg_write() are identical. We can save space and simplify the
code by converting these functions into inlines and putting them in
i2c.h.
