Enable the EC and keyboard, using the SPI bus.

The EC driver requires a particular format and a deactivation delay. Also
U-Boot does not support interrupts.

For now, adjust the device tree to comply. At some point we should tidy
this up to support interrupts and make tegra and exynos use the same setup.

At present the driver does not properly honour the requested SPI CS
deactivation delay since the SPI bus is changed in the claim_bus() method.

Everything the claim_bus() method does can be done when the device is probed
(setting the speed and mode) and at the start of a new transfer (where the
fifo_status is already cleared). So drop this method.

Also, until the delay is complete, we should not touch the bus, so make sure
that spi_cs_activate() is called before other things are done in the xfer()
method.

I might have missed something, but I failed to use the escape char '\'
in strings. To pass a printf format string like "foo %d bar\n" via
Kconfig to the code.

Right now its not possible to use the escape character '\' in Kconfig
string values correctly to e.g. set this string value "test output\n".
The '\n' will be converted to 'n'.

The current implementation removes some of the '\' chars from the input
string in conf_set_sym_val(). Examples:

'\'	-> ''
'\\'	-> '\'
'\\\'	-> '\'
'\\\\'	-> '\\'
...

And then doubles the backslash chars in the output string in
sym_escape_string_value(). Example:

'\'	-> ''	-> ''
'\\'	-> '\'	-> '\\'
'\\\'	-> '\'	-> '\\'
'\\\\'	-> '\\'	-> '\\\\'
...

As you see in these examples, its impossible to generate a single '\'
charater in the output string as its needed for something like '\n'.

This patch now changes this behavior to not drop some backslashes in
conf_set_sym_val() and to not add new backslashes in the resulting
output string. Removing the function sym_escape_string_value()
completely as its not needed anymore.

Commit 81830581 ("imx6: centralise common boot options in
mx6_common.h") broke boot on mx6sl and mx6sx by assuming that all mx6
SoCs use the same LOADADDR/SYS_TEXT_BASE range, which is not correct.

DDR on mx6sx/mx6sl starts at 0x80000000.

Adjust LOADADDR/SYS_TEXT_BASE to the proper values for mx6sx/mx6sl,
so that these SoCs can boot again.

Also, TQMA6 requires a custom CONFIG_SYS_TEXT_BASE value, so move
its setting prior to the inclusion of mx6_common.h.

Before device-tree, the device serial number used to be passed to the kernel
using ATAGs (on ARM). This is now deprecated and all the handover to the kernel
should now be done using device-tree. Thus, this passes the serial-number
property to the kernel using the serial-number property of the root node, as
expected by the kernel.

The serial number is a string that somewhat represents the device's serial
number. It might come from some form of storage (e.g. an eeprom) and be
programmed at factory-time by the manufacturer or come from identification
bits available in e.g. the SoC.
