Subject: [PATCH] ath11k: Fix incorrect debug_mask mappings

Currently a couple of debug_mask entries are mapped to the same value,
this could enable unintended driver logging. If enabling DP_TX logs was
the intention, then this could also enable PCI logs flooding the dmesg
buffer or vice versa. Fix this by correctly assigning the debug masks.

Found during code review.

Tested-on: WCN6750 hw1.0 AHB WLAN.MSL.1.0.1-00887-QCAMSLSWPLZ-1

Fixes: aa2092a9bab3f ("ath11k: add raw mode and software crypto support")
