This fixes a warning shown when phys_addr_t is 32-bit int
when compiling with clang:
mm/memblock.c:927:15: warning: implicit conversion from 'unsigned long long'
to 'phys_addr_t' (aka 'unsigned int') changes value from
18446744073709551615 to 4294967295 [-Wconstant-conversion]
r->base : ULLONG_MAX;
^~~~~~~~~~
./include/linux/kernel.h:30:21: note: expanded from macro 'ULLONG_MAX'
#define ULLONG_MAX (~0ULL)
^~~~~
