[U-Boot] [PATCH] Convert CONFIG_SYS_BOOT_GET_{CMDLINE, KBD} to Kconfig

[Derald D. Woods <woods.technical@gmail.com>]

This converts the following to Kconfig:
	CONFIG_SYS_BOOT_GET_CMDLINE
	CONFIG_SYS_BOOT_GET_KBD

Additionally, ARM now selects CONFIG_SYS_BOOT_GET_CMDLINE. This enables
the 'boot_get_cmdline' call to be reached from 'image_setup_linux' in
"common/image.c".
