Add __print_flags_u64() and the helper trace_print_flags_seq_u64() in the
same spirit as __print_symbolic_u64() and trace_print_symbols_seq_u64().
These functions allow us to print symbols associated with flags that are 64
bits wide even on 32 bit machines.

These will be used by the DAX code so that we can print the flags set in a
pfn_t such as PFN_SG_CHAIN, PFN_SG_LAST, PFN_DEV and PFN_MAP.

Without this new function I was getting errors like the following when
compiling for i386:

./include/linux/pfn_t.h:13:22: warning: large integer implicitly truncated
to unsigned type [-Woverflow]
 #define PFN_SG_CHAIN (1ULL << (BITS_PER_LONG_LONG - 1))
