efi: Add misc char driver interface to update EFI firmware
This patch introduces a kernel module to expose a capsule loader
interface (misc char device file note) for users to upload capsule
binaries.
Example:
cat firmware.bin > /dev/efi_capsule_loader
Any upload error will be returned while doing "cat" through file
operation write() function call.
