serial: sh-sci: prevent setup of uninitialized serial console
Commit 906b17dc089f7fa87e37a9cfe6ee185efc90e0da introduced a condition where the kernel will crash unless a earlyprintk parameter is specified. Without this parameter, sci_console_init is called during early console setup without any port being initialized, and the kernel crashes a little bit later when uart_set_options attemps to invoke set_termios on a port with an ops member equal to NULL. This patch just checks in sci_console_init that the port is properly initialized, and aborts the early console setup if it is not.
