[PATCH v2] efi_loader: Use sysreset instead of reset command

[Masami Hiramatsu]

Use sysreset_walk_halt() directly from reset-after-capsule-on-disk
feature to reboot (cold reset) machine instead of using reset command
interface, since this is not a command.
Note that this will make CONFIG_EFI_CAPSULE_ON_DISK depending on
the CONFIG_SYSRESET.

 Changes in v2:
  - Add CONFIG_SYSRESET dependency.
  - Fix to add #include <sysreset.h>
