sunxi: Revert "sunxi: make SoC variant choice mandatory"
This reverts commit 1a5f0de08e86("sunxi: make SoC variant choice
mandatory").
With the optional marking in the Kconfig "make savedefconfig"
will drop CONFIG_MACH_SUN4I=y from all the A10 boards, making it
hard to see at a glance which family of sunxi chips the defconfig
is for.
This commit therefore restores the optional, and restores
CONFIG_MACH_SUN4I=y to all defconfig's which had it dropped
because of this.
