cbfstool: add an option for creating a topswap bootblock

Hardware / Coreboot - Rizwan Qureshi [intel.com] - 26 June 2018 05:51 EDT

Add an option '-j' which takes the size of topswap boundary. This option serves both as a bool and a size for creating a second bootblock to be used with topswap feature in Intel CPUs. '-j' is also used in conjunction with add-master-header to update the location of cbfs master header in the second bootblock.

BUG=None BRANHC=None TEST=add bootblock entry to the image with -j option specifying different topswap sizes and also use the -j option for add-master-header.
