The interrupt status (ISR) bits of RX desc unavailable (RDU) for 8922AE
are B_BE_RDU_CH1_INT_V1 and B_BE_RDU_CH0_INT_V1. With wrong bits, if it
happens, driver can't recognize the situation and prompt a message.
Fix the definition accordingly.

The PCIE wake bit is to control PCIE wake signal to host. When PCIE is
going down, clear this bit to prevent waking up host unexpectedly.

disable EQ to improve that.

The PCI settings aren't always persistent after chip suspends, so
reconfigure the settings after chip resumes. Since most of these settings
are the same, consolidate them into a function to avoid missing somewhere.
Fix the missing case of 8922AE resume flow.

The setting during suspend or resume is different between different
generation, so update it.

The register of control and polling function for TX/RX DMA is different
from different generation, so update them. Also rename polling_dma
function to polling_dma_idle to avoid misunderstanding.

PCI CLK/ASPM/L1SS is power management mechanism used to reduce power
consumption of PCI chip. The registers for setting of these features
in WiFi 7 Chip are different from WiFi 6 chip, so separate them
in generation information.

abnormal situation more accurately, and set hardware watchdog timer to 4ms.

For WiFi 7, interrupt status registers and their definitions are changed
a lot, but the logic is still the same, so define fields to reuse the code.

At probe stage, we only do partial initialization to enable ability to
download firmware and read capabilities. After that, we use this pre_deinit
to disable HCI to save power.

Level 1 recovery is to recover TX/RX rings, so it needs PCI to stop/start
DMA. But, different chip gen have different implementations, either
register address/mask or function flow. So, configure callback of
stop/start DMA by chip gen.

Configure callback of reset BDRAM (buffer descriptor RAM) by chip gen.
Refine the one of 802.11ax chip gen and drop a redundant duplicate of it
in 802.11ax chip gen. Then, assign right callback of rst_bdram for HCI ops
which needs to do callback according to chip gen.

Call this function when doing MAC initialization at probe stage. It does
partial initial registers only, because we only need basic ability to
download firmware. The function to clear index is the sub-function,
so set its pointer as well.
