Add option to set shell prompt string from menuconfig and migrate boards globally. The migration is done as follows: - Boards that explicitly and unconditionally set CONFIG_SYS_PROMPT had the entry moved to their defconfig files. - Boards that defined some kind of #ifdef logic which selects the CONFIG_SYS_PROMPT (for example qemu-mips) got an #undef CONFIG_SYS_PROMPT right before the #ifdef logic and were left alone. - This change forces CONFIG_SYS_PROMPT to be a per board decision, and thus CONFIG_SYS_PROMPT was removed from all <soc>_common.h and <arch>_common.h files. This results in a streamlined default value across platforms, and includes the following files: spear-common, sunxi-common, mv-common, ti_armv7_common, tegra-common, at91-sama5_common, and zynq-common. - Boards that relied on <arch/soc>_common.h values of CONFIG_SYS_PROMPT were not updated in their respective defconfig files under the assumption that since they did not explicitly define a value, they're fine with whatever the default is. - On the other hand, boards that relied on a value defined in some <boards>_common.h file such as woodburn_common, rpi-common, bur_am335x_common, ls2085a_common, siemens_am33x_common, and omap3_evm_common, had their values moved to the respective defconfig files. - The define V_PROMPT was removed, since it is not used anywhere except for assigning a value for CONFIG_SYS_PROMPT.
