ARM: uniphier: remove unused init code for CONFIG_DEBUG_UART
debug_uart_init() is called from spl_board_init(), which is only
compiled for SPL. For U-boot proper, _debug_uart_init() is unreachable,
so dropped by the dead code elimination.
Now that 64-bit SoCs of this SoC family no longer support SPL,
debug-uart-ld20.c is never compiled.
