mach-ux500: cryp/hash: Updated for both u8500 & u5500

cryp1 & hash1 updated to be compatible on both u8500 and u5500:
    - added to u5500_defconfig.
    - settings from devices.c to board-mop500.c & board-u5500.c.
    - dynamic driver registration in board-mop500.c & board-u5500.c.
    - added cryp1 to clock-db5500.c and renamed cryp to cryp0.
    - added function dbx500_add_platform_device_noirq to devices-common.c.
    - added cryp1 and hash1 inline functions to devices-common.h
    (dbx500_add_cryp1).
    - defines added to devices-db5500.h and devices-db8500.h.
    - u8500_cryp/hash changed to ux500_cryp/hash.
    - update to handle different value for CRYP_PERIPHERAL_ID2 between
    u8500 and u5500 (more info in ER336742).
