powerpc/corenet_ds: Get rid of the SRIOBOOT_MASTER build target
Get rid of the SRIOBOOT_MASTER build target, and to support for serving as a SRIO boot master via environment variable. Set the environment variable "bootmaster" to "SRIO1" or "SRIO2" using the following command: setenv bootmaster SRIO1 saveenv The "bootmaster" will enable the function of the SRIO boot master, and this has the following advantages compared with SRIOBOOT_MASTER build configuration: 1. Reduce a build configuration item in boards.cfg file. No longer need to build a special image for master, just use a normal target image and set the "bootmaster" variable. 2. No longer need to rebuild an image when change the SRIO port for boot from SRIO, just set the corresponding value to "bootmaster" based on the using SRIO port.
