SceSdstor

Module
SceSdstor module does not export any functions exсept module_start.

This module is responsible for initializing all storage devices. This includes:
 * eMMC
 * Game gard
 * Memory card
 * USB Mass Storage

Based on layout of data segment and code of some subroutines (mbr table init, partition entry table init etc) it can be said that there are 5 devices in total. However only first 4 devices are known at the moment.

Types
Looks like SceSdstor driver uses its own device type
