The efi-arm case was defining its own header size calculation, even though it's
100% identical to the common EFI32_HEADER_SIZE definition.
So let's clean it up to use the common define.

For EFI images, we always have the following layout:
[PE header]
[padding]
[first section (which also is the entry point)]
Currently there are 2 places where we define how big header+padding are:
in the .vaddr_offset member of our target image definition struct as well
as in code in grub_in
In order to enforce NX semantics on non-code pages, UEFI firmware
may require that all code is EFI_PAGE_SIZE (4k) aligned. A similar
change has recently been applied to edk2 to accomodate for the same
fact:

I got a new toy this week: An HP Envy X2 system. This is one of those shiny
new Qualcomm Snapdragon based Windows tablet/notebook hybrid things.
While running Windows on those is actually not a terribly bad experience now
that WSL is out, I would like to see Linux run on those as well in the futur
There is UEFI firmware popping up in the wild now that implements stricter
permission checks using NX and write protect page table entry bits.
This means that firmware now may fail to load binaries if its individual
sections are not page aligned, as otherwise it can not ensure permission
boundarie

Dear GRUB folks,
When the module `at_keyboard` is directly into the GRUB image
(`--modules`), and GRUB is loaded really quickly, then the timer, which,
after counting down to 0 (`GRUB_TIMEOUT`), starts the selected entry, is
not shown.
I noticed this issue on the ASRock E350M1 with coreboot
