wifi: ath11k: Use platform_get_irq() to get the interrupt

Browse Source 
[ Upstream commit f117276638b7600b981b3fe28550823cfbe1ef23 ]

As of commit a1a2b7125e ("of/platform: Drop static setup of IRQ
resource from DT core"), we need to use platform_get_irq() instead of
platform_get_resource() to get our IRQs because
platform_get_resource() simply won't get them anymore.

This was already fixed in several other Atheros WiFi drivers,
apparently in response to Zeal Robot reports. An example of another
fix is commit 9503a1fc12 ("ath9k: Use platform_get_irq() to get the
interrupt"). ath11k seems to have been missed in this effort, though.

Without this change, WiFi wasn't coming up on my Qualcomm sc7280-based
hardware. Specifically, "platform_get_resource(pdev, IORESOURCE_IRQ,
i)" was failing even for i=0.

Tested-on: WCN6750 hw1.0 AHB WLAN.MSL.1.0.1-00887-QCAMSLSWPLZ-1
