Subject: [PATCH] add long variants for __ffsll

When building blender there is this error

/usr/include/nanovdb/NanoVDB.h:1880:12: error: call to '__ffsll' is ambiguous
    return __ffsll(v);
           ^~~~~~~
/usr/include/hip/amd_detail/amd_device_functions.h:70:39: note: candidate function
__device__ static inline unsigned int __ffsll(unsigned long long int input) {
                                      ^
/usr/include/hip/amd_detail/amd_device_functions.h:78:39: note: candidate function
__device__ static inline unsigned int __ffsll(long long int input) {

on a 64 bit arch uint64_t can be an unsigned long, so add the long variants
