scripts/dtc: fix '%zx' warning
dtc uses an incorrect format specifier for printing a uint64_t value.
uint64_t may be either 'unsigned long' or 'unsigned long long' depending
on the host architecture.
Fix this by using %llx and casting to unsigned long long, which ensures
that we always have a wide enough variable to print 64 bits of hex.
