Code for changing boot source is platform generic and can be used by any P1* and P2* compatible RDB board. Not only by boards which use config header file p1_p2_rdb_pc.h. So move this code from p1_p2_rdb_pc.h to p1_p2_bootsrc.h and cleanup macros for generating boot source env variables in CONFIG_EXTRA_ENV_SETTINGS. This allows to use code for resetting board and rebooting to other boot source also by other boards in future. Signed-off-by: Pali Rohár <pali@kernel.org>
