Open the Linux irq_shmem_demo host path on the libmetal UIO bus using stable logical names exposed through /sys/class/uio/uioX/name. Read the host IPI remote kick bit from the backing device-tree node through libmetal,uio-ipi-bitmask, and derive descriptor and payload sizes from the opened IO regions so the host demo no longer depends on generated device names or carveout size macros.

Remove amd_linux_userspace host-side config header generation now that the Linux demo opens fixed logical UIO devices and derives the remaining runtime values directly from libmetal IO regions and the backing device tree. Drop config.h.in and the configure-time CMake path, and update the Linux host README to document the required UIO logical names, the libmetal,ipi-remote-mask property, and the direct run flow.

Allow the Linux host irq_shmem_demo to override the default logical UIO names and the IPI remote-mask property from the command line while keeping the stable libmetal defaults. Plumb a small platform options struct through platform_init(), parse long-form host arguments in main(), and document the override flow in the host README.
