wifi: ath11k: implement SRAM dump debugfs interface
On-board SRAM contains valuable information for firmware debugging so
add a new file named "sram" to debugfs with which we can dump SRAM
content using following the following:
cp /sys/kernel/debug/ath11k/wcn6855\ hw2.0/sram /tmp/sram
Currently this feature is enabled for QCA6390 and WCN6855.
Tested-on: QCA6390 hw2.0 PCI WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1
Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-01720.1-QCAHSPSWPL_V1_V2_SILICONZ_LITE-1
