soc/amd/common/block/pci: Fix validation of pointer
Procedure write_pci_int_table() does not validates intr_data_ptr. It must
be validated together with picr_data_ptr and idx_name.
BUG=b:69868534
TEST=Build fake kahlee with intr_data_ptr not initialized, boot and see
error message. Than build correct kahlee and verify that error message
is gone.
