Subject: [PATCH 2/2] wifi: ath5k: Use platform_get_irq() to get the interrupt

For the same reasons talked about in commit 9503a1fc123d ("ath9k: Use
platform_get_irq() to get the interrupt"), we should be using
platform_get_irq() in ath5k. Let's make the switch.

I'm not setup to actually test this, but I figured that I might as
well go all the way and fix all the instances of the same pattern that
I found in the ath drivers since the old call was actually breaking me
in ath11k. I did at least confirm that the code compiles for me.

If folks would rather not land an untested patch like this, though,
feel free to drop this and just land patch #1 as long as that one
looks OK.
