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. Signed-off-by: Abner Chang <abner.chang@hpe.com> Acked-by: Anup Patel <anup.patel@wdc.com>
