This implements generic EFI core kernel code to seed the kernel entropy pool from a Linux specific UEFI configuration table containing a random seed supplied by the firmware. (#1) In addition, it wires it up for ARM and arm64, by invoking the EFI_RNG_PROTOCOL UEFI protocol from the stub, and populating such a UEFI config table using its output. How to wire this up for x86 is left as an exercise for the Intel developer.
