[PATCH] wifi: ath12k: fix debug messages

[Kalle Valo]

From: Kalle Valo <quic_kvalo@quicinc.com>

In ath12k the debug messages were broken, no matter setting what value to the
debug_mask module parameter would not get the debug messages printed. The issue
is that __ath12k_dbg() uses dev_dbg() to print the debug messages which requires either enabling
CONFIG_DYNAMIC_DEBUG or DEBUG symbol in the driver.

ath12k is supposed to use debug_mask module to control whether debug messages
are printed or not. Using both CONFIG_DYNAMIC_DEBUG and debug_mask parameter
does not make any sense so switch to using dev_printk(), just like ath11k does.
Now it's enough just to debug_mask module parameter to get the debug messages.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1
