Subject: [PATCH 15/42] PCI: aardvark: Change name of INTx irq_chip to advk-INT

This name is visible in /proc/interrupts file and for better reading it
should have at most 8 characters. Also there is no need to allocate this
name dynamically, since there is only one PCIe controller on Armada 37xx.
This aligns with how the MSI irq_chip in this driver names it's interrupt
("advk-MSI").
