DCDC5 and DCDC6 supply rtc and need to be on for accessing the module.
On A1 revision of the TPS65218, FSEAL bit would be undefined without
coin-cell present which in many cases led to it being set, causing DCDC5
and DCDC6 to stay active, but also leading to unexplained failures when
it was not. On B1 revision, FSEAL is always 0 when no coin-cell is present
so this patch is required on boards with B1 revision to ever work. This
implementation works on boards with either A1 or B1 revision and makes
sure that DCDC5 and DCDC6 always stay active.

System crash was observed if one of the driver initialisation
commands is timed out. The reason is our timeout handler triggers
firmware dump, meanwhile driver initialisation error paths have
already freed the adapter structure.
Firmware hasn't yet completely initialized. So collecting firmware
dump is not needed in this case. Command timeout handler is
modified in this patch to fix the crash issue.

We enable Rx data by updating RX ring read pointer in

600f5d909a54("mwifiex: cleanup ioctl wait queue and abstraction layer")
introduced the wakeup_interruptible suppression in mwifiex_complete_cmd
b1a47aa5e1e1("mwifiex: fix system hang issue in cmd timeout error case")
then added wakup_interruptible to mwifiex_cmd_timeout_func the single
place setting a status of ETIMEDOUT.
Instead of doing extra work, using the standard call-chain will have the
same effect:
mwifiex_cancel_pending_ioctl
-> mwifiex_recycle_cmd_node
-> mwifiex_insert_cmd_to_free_q
-> mwifiex_complete_cmd
-> wake_up_interruptible
The difference is that previously the condition was not set to true,

have any consequence

CMD_F_CANCELED was used to abort mwifiex_process_cmdresp in
case it already started or starts processing the cmd.
But this was probably not working the way intended:
- it is racy: mwifiex_process_cmdresp might already have passed that
test and is continuing to use the cmd node being recycled
- mwifiex_process_cmdresp repeatedly uses adapter->curr_cmd which
we just set to NULL
- mwifiex_recycle_cmd_node will clear the flag
The reason why it probably works is that mwifiex_cancel_pending_ioctl
is only called from mwifiex_cmd_timeout_func, where the there is little
chance of a command response still arriving

Allow network stack part of Rx processing to run on separate core,
relaxing CPU utilization on the core used for Rx NAPI.
If RXHASH feature is enabled, the driver sets rxhash of each skb to 1
to enable RPS. The core for processing the rx skb is determined by RPS
mechanism according to rx_cpus bit mask which is configured at user level.
For processing skbs on different core from the core which processes
the interrupts, it is recommended not to enable core 0 in rx_cpus bit mask.
