crypto: ccree - use existing helpers to split 64-bit addresses
Use the existing lower_32_bits() and upper_32_bits() macros instead of explicit casts and shifts to split a 64-bit address in its two 32-bit parts. Drop the superfluous cast to "u16", as the FIELD_PREP() macro already masks it to the specified field width.
