stand: Move sections around to fix stand/ build with ld.lld on armv7

Browse Source 
When building loader bits, lld fails with the following error:
"ld: error: section: .dynamic is not contiguous with other relro sections"
on both ubldr and EFI loader.

Move .dynamic up to make ld.lld happy, adjust .got as necessary for ubldr.

Tested on:	OrangePi One (ld.lld, ubldr)
Tested on:	Banana Pi-M3 (ld.lld, ubldr)
Tested on:	qemu-armv7 (ld.lld, EFI)
Tested on:	qemu-armv7 (ld.bfd, EFI)
Tested on:	Raspberry Pi 2 (ld.bfd, ubldr) [manu]
Tested on:	Banana Pi-M2 (ld.bfd, ubldr) [manu]
