lib: utils/serial: remove semihosting_putc

Browse source 
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.
