openocd: fix simple cases of Yoda condition

There are ~900 Yoda conditions to be aligned to the coding style.
For recurrent Yoda conditions it's preferable using a trivial
script in order to minimize the review effort.
E.g. comparison of uppercase macro/enum with lowercase variable:
	- ...(ERROR_OK == retval)...
	+ ...(retval == ERROR_OK)...

Patch generated automatically with the command:
	sed -i \
	's/(\([A-Z][A-Z0-9_]*\) \([=!]=\) \([a-z][a-z0-9_]*\))/(\3 \2 \1)/g' \
	$(find src/ -type f)

While there, remove the braces {} around a single statement block
to prevent warning from checkpatch.
