[PATCH 2/2] lib: utils/serial: remove semihosting_putc

[Xiang W]

For some debuggers that do not implement SYSWRITEC and SYSREADC
operations, we can use SYSWRITE and SYSREAD instead like the
implementation of semihosting_putc(). This makes
semihosting_putc/semihosting_puts similar. Since
console_putc/console_puts are now interchangeable, removing the
semihosting_putc.
