Correct settings of PCI from the latest internal fixes.
Chin-Yen Lee (2):
wifi: rtw89: correct enable functions of HCI/PCI DMA
wifi: rtw89: pci: concentrate control function of TX DMA channel
Zong-Zhe Yang (1):
wifi: rtw89: 8852c: L1 DMA reset has offloaded to FW

2.25.1
From: Chin-Yen Lee <[email protected]>
Some PCI and MAC registers are changed for different
chips and correct them accordingly. And HCI MAD functions
belongs to MAC core, so move it to mac.h/.c.

are offloaded to FW L1 reset flow. So, driver no longer needs to do them.
