Refactor (clean up) the code in riscv_semihosting.c by moving
the magic sequence detection to its own function.
Cleanup the debug prints denoting the semihosting outcome
so that they are easier to understand when reading the OpenOCD's
verbose (debug) log.
Use le_to_h_u32() to convert memory buffer to instruction code
because RISC-V instructions are always little endian.
(target_buffer_get_u32() was incorrect for that reason.)
