regulator: da9063: fix null pointer deref with partial DT config
When some of the da9063 regulators do not have corresponding DT nodes
a null pointer dereference occurs on boot because such regulators have
no init_data causing the pointers calculated in
da9063_check_xvp_constraints() to be invalid.

Do not dereference them in this case.
