zynqmp: Run board_get_usable_ram_top() only on main U-Boot

With commit ce39ee28ec31 ("zynqmp: Do not place u-boot to reserved memory
location"), the function board_get_usable_ram_top() is allocating
MMU_SECTION_SIZE of about 2MB using lmb_alloc(). But we dont have this
much memory in case of mini U-Boot.

Keep these functions which use lmb under CONFIG_LMB so that they are
compiled and used only when LMB is enabled.
