[ptxdist] [PATCH v2] optee: switch optee cfg string to config file

[Michael Grzeschik <m.grzeschik@pengutronix.de>]

The current situation of one string containing all config options in one
line is nearly impossible to handle inside of the BSPs platformconfig.
Every change in that line makes the diff heavy to parse for differences.

This patch is switching the rule to load one config file
that contains a list of set config variables instead of that
one bulky line.

Just like barebox and kernel the optee config will be located in the
platformdir and be named as optee.config as default.

Signed-off-by: Michael Grzeschik <m.grzeschik@pengutronix.de>

v1 -> v2:
 - made optee.config a fixed file instead of an option
 - added an warning to move the string variables to the new file format
