gsm0480: copy the raw USSD data, its DCS and length
As it was already documented before, the 'ss_request' struct has a rudiment of deprecated 'ussd_request' struct - the 'ussd_text' field. It represents the data either of an INVOKE component, either of a RETURN_RESULT component, encoded as ASCII in case if DCS is 0x0f (i.e. decoded by the code itself), otherwise raw bytes 'as is'. Previously, there was no possibility to distinguish between ASCII and raw bytes with different DCS. Moreover, the payload decoding is not desired in some cases. Let's introduce the new fields, which will carry the raw unmodified payload, its length and DCS (Data Coding Scheme). Change-Id: Ia193d175021e145bb3b131290231f307dbefc64a
