As this symbol can either be a fixed value or the function get_board_ddr_clk, migration is tricky. Introduce a choice of DYNAMIC or STATIC_DDR_CLK_FREQ. If DYNAMIC, we continue to use the board defined get_board_ddr_clk function. If STATIC, set CONFIG_DDR_CLK_FREQ to that value and now include/clock_legacy.h contains the function prototype or defines get_board_ddr_clk() to that static value. Update callers to test for DYNAMIC or STATIC. Signed-off-by: Tom Rini <trini@konsulko.com>

The DDR clock frequency can either be defined statically now at

build time, or can be determined at run-time via the

get_board_ddr_clk function.
