efi(4): Implement MI parts of EFIIOC_GET_TABLE. Intended to be compatible with FreeBSD. Not yet supported on any architectures. PR kern/57076 XXX pullup-10

/* $NetBSD: efivar.h,v 1.2 2023/05/22 16:27:58 riastradh Exp $ */
efi: Add /dev/efi character device Introduce a /dev/efi character device that provides a means for accessing UEFI RT variable services from userland. Compatible with the FreeBSD ioctl interface for ease of porting their libefivar and associated tools. The ioctl interface is defined in sys/efiio.h. To enable support for this on an arch, the kernel needs `pseudo-device efi` and the MD EFI implementation needs to register its backend by calling efi_ops_register(). This commit includes an implementation for Arm.
