Javier Martinez Canillas e5be30174c util/mkimage: Some fixes to PE binaries section size calculation 
Commit f60ba9e594 (util/mkimage: Refactor section setup to use a helper)
added a helper function to setup PE sections, but it caused regressions
in some arches where the natural alignment lead to wrong section sizes.

This patch fixes a few things that were caused the section sizes to be
calculated wrongly. These fixes are:

 * Only align the virtual memory addresses but not the raw data offsets.
 * Use aligned sizes for virtual memory sizes but not for raw data sizes.
 * Always align the sizes to set the virtual memory sizes.

These seems to not cause problems for x64 and aa64 EFI platforms but was
a problem for ia64. Because the size of the ".data" and "mods" sections
were wrong and didn't have the correct content. Which lead to GRUB not
being able to load any built-in module.
