gsm-fw/L1: fix for the DSP patch corruption bug The L1 code we got from the LoCosto fw contains a feature for DSP CPU load measurement. This feature is a LoCosto-ism, i.e., not applicable to earlier DBB chips (Calypso) with their respective earlier DSP ROMs. Most of the code dealing with that feature is conditionalized as #if (DSP >= 38), but one spot was missed, and the MCU code was writing into an API word dealing with this feature. In TCS211 this DSP API word happens to be used by the DSP code patch, hence that write was corrupting the patched DSP code.

Changes from loadtools-r1 to loadtools-r2:

* A flash ID check has been implemented in fc-loadtool, invoked automatically
  before doing any erase or program operations, or explicitly at any time with
  the flash info command.  This check ensures that the type of flash chip in
  the target GSM device is the same as what loadtool thinks it is, based on the
  hardware parameters file.

* fc-xram command line syntax changed slightly in order to support immediate
  passing of the serial line to rvinterf/rvtdump.

* Miscellaneous minor polish.
