[U-Boot] [PATCH v4 15/42] common: Move serial_printf() to the serial header

[Simon Glass]

Move this function header to serial.h since this function is clearly
related to serial. The function itself stays in console.c since we don't
have a single serial file. DM and non-DM each has a separate file so we
would have to either create a new common serial file, or repeat the
function in both serial.c and serial-uclass.c, neither of which seem
worthwhile.
