Saved 872 btyes of ram by moving variables to code

Before this patch for Taranis target (classic newlib):
```
   text	   data	    bss	    dec	    hex	filename
 381472	   3344	  48500	 433316	  69ca4	opentx.elf
```
After this patch:
```
   text	   data	    bss	    dec	    hex	filename
 382296	   2552	  48420	 433268	  69c74	opentx.elf
```
Savings:
* data saving: 3344-2552=792
* bss saving: 48500-48420=80 

Everything still seams to be working, but please test before merging!
