From fa6fd6bf86e97140cf3c991f605cf04a0b24ab50 Mon Sep 17 00:00:00 2001
From: Abner Chang <abner.chang@hpe.com>
Date: Sat, 29 Jun 2019 16:18:04 +0800
Subject: include: Move callbacks in sbi_platform to separate struct
Move platform opensbi functions to sbi_platform_operations structure.
Both sbi_platform and sbi_platform_operations structures are maintained
by platform vendors.
