Subject: [Patch] cris: add arch/cris/include/asm/serial.h

This fixes the following build errors:

src/drivers/tty/serial/8250_early.c:160: error: 'BASE_BAUD' undeclared (first use in this function): 1 errors in 1 logs
        v3.0/cris/cris-allyesconfig
src/drivers/tty/serial/8250_early.c:160: error: (Each undeclared identifier is reported only once: 1 errors in 1 logs
        v3.0/cris/cris-allyesconfig
src/drivers/tty/serial/8250_early.c:160: error: for each function it appears in.): 1 errors in 1 logs
        v3.0/cris/cris-allyesconfig
src/drivers/tty/serial/8250_early.c:37:24: error: asm/serial.h: No such file or directory: 1 errors in 1 logs
        v3.0/cris/cris-allyesconfig

I am not sure if (1843200 / 16) is suitable for cris, but
most of other arch's define it as this value.
