hwstub/jz4760b: add lua code to probe for ei/di and ext instructions
Add lua code to check whether ei/di and ext instructions are supported. This
is unclear since xburst is somewhere between mips32r1 and mips32r2. Details
results are below, but in summary: they don't work (ei has no effect, di/ext
cause illegal instruction exceptions)
> ./hwstub_shell -q -b -e 'require("jz/misc"); JZ.misc.enable_sram()' \
-f lua/xburst.lua -e "XBURST.test_ext_inst(0xb32d0000)"
