[PATCH 19/28] net: wireless: ath10k: Use references to INTX instead of LEGACY

Damien Le Moal
2024-03-25T07:11:01Z

To be consistent with the deprecation of PCI_IRQ_LEGACY and its
replacement with PCI_IRQ_INTX, rename macros and functions referencing
"legacy irq" to instead use the term "intx irq".
