irqdomain: Fix debugfs formatting
This patch fixes the irq_domain_mapping debugfs output to pad pointer values with leading zeros so that pointer values are displayed correctly. Otherwise you get output similar to "0x 5e0000000000000". Also, when the irq_domain is set to 'null' Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Cc: David Daney <david.daney@cavium.com> Cc: Mika Westerberg <mika.westerberg@linux.intel.com>
