This adds some missing IOMMU related options for x86/64 and moves some
of them to generic for all targets.
On x86 IOMMU_DEFAULT_DMA_LAZY is used by default, on all other platforms
IOMMU_DEFAULT_DMA_STRICT is the default. we just follow the default
kernel configuration here.

Enable IOMMU support for Intel and AMD x86 platforms. With this, when the
vfio module is present, physical PCI devices can be passed to VMs, for
example with `qemu-system-x86_64 -device vfio-pci,host=05:00.0 ...`.
IOMMU support increases the kernel size by a small amount (~370KB, from
5239840 B to 5611200 B, a ~7% increase in size).

All targets expect the malta target already activate the CONFIG_GPIOLIB
option. Move it to generic kernel configuration and also activate it for
malta.

Starting with GCC 12, we have the possibility of mitigating straight-line
speculation vulnerabilities in x86-64 targets. Make it so.

This is now built-in, enable so it won't propagate on target configs.
