tegra: spi: Drop the claim_bus() method to correct delays
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.

Kconfig: Enable usage of escape char '\' in string values
I might have missed something, but I failed to use the escape char '\'

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:
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

output string. Removing the function sym_escape_string_value()
completely as its not needed anymore.

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.
