Description

Once we have the new GSM firmware, we should add code to query the GSM Modem for
hardware revision and serial number information and use this as basis for
ATAG_REVISION and ATAG_SERIAL as well as the 'iSerial' string of the USB device
code.

this should now be quite easy since we already have all the pieces in place to
talk with the GSM modem (terminal mode, passthrough, power up/down).

Using AT+CGMR can get the info, so try to send this command at u-boot
AT+CGMR
+CGMR: "HW: GTA01Bv4, GSM: gsm_ac_gp_fd_pu_em_cph_ds_vc_cal35_ri_36_amd8_ts0-Moko1"
