With the recent kernel upgrade to 6.4, swiotlb_init() path is taken
because of the new kernel config CONFIG_DMA_BOUNCE_UNALIGNED_KMALLOC,
which is enabled by default. But this should not done for trusted VMs
supported on Sun and Pineapple VMs, as these VMs would be using carveout
swiotlb memory set up separately by virtio mmio driver through the
feature CONFIG_SWIOTLB_NONLINEAR. Hence, add swiotlb=noforce kernel
command line to disable generic swiotlb setup/init for VMs. Without
this option set, VM boot up failure is observed.
