ath10k: add support for firmware crash recovery on SDIO chip

Browse source

The command to simulate firmware crash:
echo soft > /sys/kernel/debug/ieee80211/phy0/ath10k/simulate_fw_crash

It will send WMI_FORCE_FW_HANG_ASSERT to firmware, then it will trigger
CPU interrupt status register for SDIO chip, ath10k driver need to
configure it while enable SDIO interrupt, otherwise ath10k driver will
not get the assert error info.

After this change, it will success for simulate firmware crash.

Tested with QCA6174 SDIO with firmware
WLAN.RMH.4.4.1-00007-QCARMSWP-1.
