msm8660: on radio version check, support more than 1 version format per model

  * up until now, all radios for a particular model followed a certain format:
    e.g. I727: UCMC1 or I727R: UXUMA7  (4 or 5 letters followed by a number)
  * exhilarate now has two radios that work but have different version formats:
    UCAMK1 and UCLH3   (4 AND 5 letters followed by a number)
  * add the ability to take in more than 1 minversion for each model
  * only compare versions that match in format
  * error (disallow flash) if installed radio's version format is not
    understood
