libpayload: Add div_round_up() function
The lack of a div_round_up() function in libpayload keeps being a problem for payloads and has already caused us to sprinkle numerous less-readable ALIGN_UP(n, d) / d throughout depthcharge. Let's add this so we can avoid adding any more and then maybe cocchinelle them all over later.
