[PATCH 18/30] PCI: tegra: Change PRSNT_SENSE irq log to debug

[Manikanta Maddireddy <mmaddireddy@nvidia.com>]

PRSNT_MAP bit field is programmed to update the slot present status.
PRSNT_SENSE irq is triggered when this bit field is programmed, which is
not an error. Add a new switch case to trap RSNT_SENSE code and print it
with debug log level.
