[PATCH] ath10k: use 64-bit crash dump timestamps
From: Arnd Bergmann <arnd@arndb.de>

Jeff Johnson, Linus Torvalds
The dump format uses 64-bit timestamps already, but calling getnstimeofday() only returns a 32-bit number on 32-bit architectures, so that will overflow in y2038. This changes it to use ktime_get_real_ts64() instead.
