Subject: [PATCH 4/5] imsm: detail_platform_imsm supports Intel SAS controller (isci driver)

Added support in detail_platform_imsm for Intel (R) SAS controller.
Function supports AHCI and ISCI controllers. RAID properties are derived
from common OROM for both types.

Based on code From: Artur Wojcik
