configs: vf610: increase maximum size and enforce correct limit
On Vybrid SoCs U-Boot gets loaded into GFX SRAM which is 512KiB.
Currently 32KiB is reserved for the IMX header. However, this is
not reflected in the size limit. In v2017.11-rc2 the actual size
limit (512KiB-32KiB) has been reached for Colibri VF61, which
lead to a successful build of U-Boot but not a working binary.
The IMX header is much smaller than 32KiB, typically around 1KiB.
Decrease the reserved size to 4KiB and specify the correct U-Boot
size limit. Apply this new base address and limit for all Vybrid
based boards.

efi_loader: Disable env_save() call on boot
With the introduction of EFI variable support, we also wanted to persist
these EFI variables. However, the way it was implemented we ended up
persisting all U-Boot environment variables on every EFI boot.
That could potentially lead to unexpected side effects because variables
that were not supposed to be written to persisted env get written. It also
means we may end up writing the environment more often than we should.
For this release, let's just disable EFI variable persistence and instead
implement it properly for the next one.

seems turning off turbo mode on the processor does not expose this

S3 suspend/resume sometimes causes the Ubuntu kernel hang forever.
The issue is however not reproduced with a kernel built from i386/

The unstability is actually caused by unexpected interrupts being
generated during the S3 resume. For some unknown reason, FSP (gold4)
for BayTrail configures the GPIO DFX5 PAD to enable level interrupt
(bit 24 and 25). As this pin keeps generating interrupts during an
S3 resume, and there is no IRQ requester in the kernel to handle it,
the kernel seems to hang and does not continue resuming.
