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 Signed-off-by: Iain Paton <ipaton0@gmail.com> [hdegoede@redhat.com s/CONFIG_SYS_CLK_FREQ/CONFIG_TIMER_CLK_FREQ/ for the arch-timer clk speed on sun7i to fix mis-compile on sun7i] Acked-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com>
