With the FEL entry point converted to assembly code (which uses ARM
mode), the rest of the SPL can be now compiled in Thumb2 mode safely.
This provides a significant code size reduction:

== before ==
   text	   data	    bss	    dec	    hex	filename
  13938	    440	     28	  14406	   3846	spl/u-boot-spl

== after ==
   text	   data	    bss	    dec	    hex	filename
  10918	    440	     28	  11386	   2c7a	spl/u-boot-spl
