drm/i915: Iterate over pipes and skip the disabled one

It should not be assumed that a disabled display pipe will be
always last the pipe.
for_each_pipe() should iterate over I915_MAX_PIPES and check
for the disabled pipe and skip that pipe so that it should not
initialize the intel crtc for any disabled pipes.

Due to changes in for_each_pipe() macro, it requires to handle
the below compilation error.
"suggest explicit braces to avoid ambiguous ‘else’
[-Werror=dangling-else]"

v2:
- Cosmetic changes, removed unwanted parentheses. [Ville]
