marvell: octeontx2: build error: unknown type name 'u64'

Building an allmodconfig kernel arm64 kernel, the following build error
shows up:

In file included from drivers/crypto/marvell/octeontx2/cn10k_cpt.c:4:
include/linux/soc/marvell/octeontx2/asm.h:38:15: error: unknown type name 'u64'
   38 | static inline u64 otx2_atomic64_fetch_add(u64 incr, u64 *ptr)
      |               ^~~

Include linux/types.h in asm.h so the compiler knows what the type
'u64' are.
