Subject: 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.

scripts/dtc/checks.c: In function 'check_simple_bus_reg':
scripts/dtc/checks.c:876:2: warning: format '%zx' expects argument of type 'size_t', but argument 4 has type 'uint64_t' [-Wformat=]
snprintf(unit_addr, sizeof(unit_addr), "%zx", reg);
