[vs]: Update swiotlb buffer size to support multi-asic VS platform. (#6674) Current mutli-asic vs hwsku consists of 6 asics with each asic having 32 interfaces. When bringing this up, below issue was seen: When all 32 interfaces in each namespace (sonic interfaces and linux interface) is set to 9100 mtu, DMA error is seen "DMA: Out of SW-IOMMU space for 4096 bytes at device 0000:06:03.0" which can be fixed by updating swiotlb=65536 in /host/grub/grub.cfg .
