lib: utils/serial: remove semihosting_putc
For some debuggers that do not implement SYSWRITEC and SYSREADC operations, we have to use SYSWRITE and SYSREAD. Instead of implementing semihosting_putc() using SYSWRITE, let us simply remove semihosting_putc() because console_putc/console_puts are now interchangeable.
