* This function is used to fill a buffer with a decoded string representation
* of register's value.
* @param buf If non-NULL, the buffer to write the string into.
* Otherwise, the function does not perform any writes,
* it just calculates the number of characters used.
* @param reg_ordinal
* The ordinal of the register.
* @param context The structure, containing the information about the target,
* necessary to decode the register.
* @param value The value to be decoded.
*
* Returns the number of characters used by the string representation
* (excluding '\0').
*
* Example:
* const struct riscv_debug_reg_ctx_t context = {
* .abits = { .value = <abits value>, .is_set = true }
* };
* char buf[riscv_debug_reg_to_s(NULL, DTM_DMI_ORDINAL, context, <dmi value>) + 1]
* riscv_debug_reg_to_s(buf, DTM_DMI_ORDINAL, context, <dmi value>);
