[PATCH 05/40] cpu/cris: Add u-stall virtual unit to CRIS v32

[Tsukasa OI]

Because CRIS v32 model does not define u-stall virtual unit, CGEN-generated
sim/cris/decodev32.h does not define the function declaration of
crisv32f_model_crisv32_u_stall.

It led to a hack in commit 4e6e8ba7c565 ("sim: cris: clean up missing func
prototype warnings"), manually adding the declaration of
crisv32f_model_crisv32_u_stall.

To **not** touch CGEN-generated files manually, this commit adds u-stall
virtual unit for CRIS v32 to let CGEN generate the function declaration of
crisv32f_model_crisv32_u_stall automatically.

This is still hackish but less than the previous one.
