[U-Boot] [PATCH] fdt_resize(): Expand to next page boundary independent of offset

[Peter Korsgaard]

fdt_resize() adjusted the fdt totalsize so the fdt would end on a
page boundary in memory - E.G. the amount of padding depended on
the location of the fdt (offset within page).

This doesn't work very good with multi file images where the fdt
is located after the kernel and hence on a more-or-less random
offset within a page.

Instead, simply pad fdt to the next page boundary.

For the common case of fdt at offset 0 within a page, the same amount
of padding as before is added.
