Local variable is used to store cpumask to send it to
irq_set_affinity_hint and qdf_dev_set_irq_affinity APIs.
This memory is used by the kernel later outside the

As part of WIN BMI modularization, hif_bmi_register_callbacks
are removed from if_pci.c in qcacmn project. As a result,
MCL needs to invoke hif_bmi_register_callbacks in qcacld project.

so that SDIO and USB products can build when WLAN_FEATURE_BMI is
defined.

1. Modifications for SDIO HIF interface with stack.
Mailbox based devices do not use the SDIO abstraction layer.
So, devices like QCA6174, QCA9379 etc are to interface with
the SDIO stack directly, even if the CNSS wrappers are used.
ADMA based devices use the SDIO abstraction layer. So, devices
like QCN7605 do not interface with the SDIO stack directly.
2. Remove redundant osdrv layer and refactor the functions
3. Propagate hif context to all the interface functions in hif

GRO aggregations are hanging out of NAPI instance and we cannot use the
hif NAPI instance in Rx thread as gro_list inside NAPI is flushed out
at the start and end of NAPI poll, this will corrupt the gro_list on
which rx_thread is working. Address this concern by creating dummy
NAPI instances mapping to each hif NAPI and by not scheduling them.

When the wlan driver is suspending, the last thing it does is check to
see if the firmware has indicated a wakeup during the suspend process.
This is done by checking the initial wakeup flag, which is set when a
specific copy engine payload is received from firmware. For the new
dedicated wake MSI, only the wake signal is received, no payload. When
the wake MSI is toggled, set the initial wakeup flag to prevent race
conditions during the suspend process.
