Nothing inside the resource struct needs to be mutable. Sprinkle
'const' all over it. A lot of 'const'.

We already have 'const struct venus_resources'. Is that not sufficient?

Maybe it's just style, since the string arrays are const?

This doesn't error on:

	const char *pmdomains[] = { "venus", "vcodec0", "vcodec1" };
	struct venus_resources res;
	res.vcodec_pmdomains = pmdomains;
	res.vcodec_pmdomains = NULL;
