sunxi: use CONFIG_SYS_CLK_FREQ to set cpu clock

make the CPU clock selectable via Kconfig

this removes the sunxi specific CONFIG_CLK_FULL_SPEED defined in each
soc header and replaces it's use in board/sunxi/board.c with
CONFIG_SYS_CLK_FREQ from Kconfig which allows us to configure board
specific frequency on boot
