efi: stub: Change _debug_uart_putc function to inline
Update definition of _debug_uart_putc to static inline.
This will allow to avoid compilation warnings about unused code
after introduction of patch changing debug uart functions to
dummies if CONFIG_DEBUG_UART is not set.
This also matches the instructions in include/debug_uart.h and
provides consistency with implementations for other platforms.
