drivers: caam: Fix alignment fault caused by caam_desc_pop()

Size of each JR Output ring entry is of 12 bytes for CAAM
using address pointer size as 64 bit. The descriptor address
pointer thus lies at 32 bit boundary in second output ring entry.
64 bit access of descriptor pointer at 32 bit boundary generates
alignment fault. To fix this, descriptor address pointer should
be accessed as two 32 bit operations.
