Petr Štetiar a2728a806a tplink-safeloader: fix C7v5 factory flashing from vendor fw > v1.1.x 
Currently it's not possible to flash factory images on devices shipped
with vendor firmware versions 1.1.0 Build 20201120 rel. 50406 (published
2020-12-22):

 (curFw_ver, newFw_ver) == (1.1, 1.0) [NM_Error](nm_checkSoftVer) 00848: Firmwave not supports, check failed.
 [NM_Error](nm_checkUpdateContent) 01084: software version dismatched
 [NM_Error](nm_buildUpgradeStruct) 01188: checkUpdateContent failed.

They've even following note in release notes:

 Note: You will be unable to downgrade to the previous firmware version
       after updating this firmware.

This version check in vendor firmware is implemented in
/usr/bin/nvrammanager binary likely as following C code[1]:

 sscanf(buf, "%d.%d.%*s",&upd_fw_major, &upd_fw_minor);
 ...
 if (((int)upd_fw_major < (int)cur_fw_major) ||
     ((ret = 1, cur_fw_major == upd_fw_major && (upd_fw_minor < (int)cur_fw_minor)))) {
       ret = 0;
       printf("[NM_Error](%s) %05d: Firmwave not supports, check failed.\r\n\r\n","nm_checkSoftVer" ,0x350);
 }
 ...
 return ret;

So in order to fix this and make it future proof it should be enough to
ship our factory firmware images with major version 7 (lucky number).

Tested on latest firmware version 1.1.2 Build 20210125 rel.37999:

 Firmwave supports, check OK.
  (curFw_ver, newFw_ver) == (1.1, 7.0) check firmware ok!

Flashing back to vendor firmware
c7v5_us-up-ver1-1-2-P1[20210125-rel37999]_2021-01-25_10.33.55.bin works
as well:
