wifi: ath5k: Use platform_get_irq() to get the interrupt

Browse Source 
[ Upstream commit 95c95251d0547b46d6571e4fbd51b42865c15a4a ]

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"). ath5k seems to have been missed in this effort, though.
