Do reviewers get a deadline for reviewing a Paper, if yes, how much? Do reviewers/editors receive a deadline for reviewing a paper?
I wanted to know that whether reviewers/editors receive any kind of deadline for reviewing a manuscript for a journal or they are allowed to submit their reviews any time they wish since they are not paid for this service.
If they do receive a deadline what is the average time the reviewers get for evaluating the following in journals owned by Elsevier, Springer, World Scientic, Taylor &amp; Francis etc.

Round 1 revision or first review of a paper
Major Revision
Minor Revision

I find that if a major revision is required then the authors receive a time  of 2 months for fixing it.
For a minor revision the authors get a time of 1 month.
What is the time given by the journal authorities to the Editors/Reviewers for checking a major revision and a minor revision?
Can someone please let me know as one of my manuscript is in major and other in minor revision?
Any help will be greatly appreciated.
In general when journals contact potential reviewers, they do tend to give a time frame they expect those who accept to receive a review back in. The more enlightened ones also give a time limit to accept the review. As has been noted in the comments, the length of these windows varies by subject and by journal, with mathematics journals noted as being at the long end, and some disreputable science and engineering journals at the short end. In practice, these are soft targets, and editors tend to be happy if they get any response at all, even a late one. My experience is that these windows tend to be the same for initial and subsequent reviews, but I definitely won´t claim that is universal.
Note that for resubmissions there is a strong preference to reuse the original reviewers, since they are in the best position to check that their criticisms have been addressed. Having a strict deadline for review would be likely to slow the process further, since new reviewers would have to be found (and given a new block of time to respond in), who might easily raise points ignored under the original review.
One misapprehension in your question is in assuming that these targets are set by the publisher. In general it will be the senior editors making the decision based on the volume of submissions they have available, and the standard of impact they are aiming to maintain. The exceptions are at the predatory end of the market, and no reputable journal is going to publish an article unreviewed, just because all the reviewers were late responding. Modern editional systems have made life a bit easier by automating reminder emails, but these are often treated as spam messages by the recipient. Your principal solace is that many of these systems track review times and quality, and push editors to request reviews from fast, high quality reviewers.
As an author, your most useful data is average time from submission to publication, which many journals now advertise to win custom. Note that tis is a figure which can be manipulated however, by techniques such as forcing revisions to be treated as a new submission, or by giving up of articles which have sat for a long time.
