Subject: [PATCH 2/2] arm64: efi: Pass reboot cmd parameter to efi_reboot()

From: Sumit Garg <sumit.garg@....qualcomm.com>

EFI ResetSystem runtime service allows for platform specific reset type
allowing the OS to pass reset data for the UEFI implementation to take
corresponding action. So lets pass the reboot cmd parameter for the EFI
driver to determine whether it's a platform specific reset requested or
not.
