[PATCH] microblaze: spl: drop boot_linux and disable falcon mode by default

[Ovidiu Panait <ovpanait@gmail.com>]

Make spl_start_uboot() available only if CONFIG_SPL_OS_BOOT is enabled
and drop boot_linux, as the variable is not assigned anywhere.

Also, disable CONFIG_SPL_OS_BOOT in defconfig so that a
microblaze-generic_defconfig build will still boot into u-boot proper, as
it does currently.
