a4857688c3 qemuboot: reduce default size of software I/O translation buffer
With 6.5+ (specifically, if DMA_BOUNCE_UNALIGNED_KMALLOC is set) the
SWIOTLB is used, and it defaults to 64MB. This is too much when there's
only 256MB of RAM, so request 0 slabs and lets the kernel round up to
the appropriate minimum (1MB on aarch64, typically). In virtual hardware
there's very little need for these bounce buffers, so the 64MB would be
mostly wasted.

71282bbc53 qemuboot: Update hardcoded path to match new layout
Obviously this code is horrible and shouldn't hardcode it. Update it to match
the WORKDIR change to drop PE/PR for now.

afcd4b9cbc qemuboot/runqemu: Fix 6.2 and later kernel network device naming
With kernel 6.2 and later network devices are renamed by systemd. This does not
match with the current network device naming assumed in our configuration.

We may or may not change that naming but for now, pass the right kernel commandline
so things work as expected with newer kernels and removing a blocker on upgrading
to the 6.4 kernel by default.

80b0e933a0 qemuboot.bbclass: make sure runqemu boots bundled initramfs kernel image
The QB_DEFAULT_KERNEL is set to pick bundled initramfs kernel image
if the Linux kernel image is generated with INITRAMFS_IMAGE_BUNDLE="1".

This makes runqemu to automatically pick bundled initramfs kernel image
instead of explicitly mentioning bundled initramfs kernel image in
runqemu.

Move classes to classes-global or classes-recipe as appropriate to take
advantage of new bitbake functionality to check class scope/usage.
