'interrupt-parent' is often documented as part of define bindings, but
it is really outside the scope of a device binding. It's never required
in a given node as it is often inherited from a parent node. Or it can
be implicit if a parent node is an 'interrupt-controller' node. So
remove it from all the binding files.

The bus + bmi-chip-id + bmi-board-id is not enough to identify the correct
board data file on QCA4019 based devices. Multiple different boards share
the same values. Only the original reference designs can currently be
identified and loaded from the board-2.bin. But these will not result in
the correct calibration data when combined with the pre-calibration data
from the device.
An additional "variant" information has to be provided (via SMBIOS or DT)
to select the correct board data for a design which was modified by an ODM.

The example in the BCM43xx documentation uses "brcmf" as node name.
However, wireless devices should be named "wifi" instead. Fix this to

adjust only the board specific bits).

The ESP8089 chips can mostly be enumerated via their sdio interface,
but they are clocked by an external crystal which may differ from one
board to the other.
This commit adds a binding for the sdio child node for these chips,
allowing to specify the external crystal type (for now, this binding
could be be extended with e.g. OOB irq support later).
The Android driver for this chip uses a text file with key,value pairs
which gets loaded as firmware to pass this info to the firmware.
The "esp,crystal_26M_en" name is chosen to match the crystal_26M_en
key-name in that text file.
Note that at this point there only is an out of tree driver for this
hardware, there is no clear timeline / path for merging this. Still
I believe it would be good to specify the binding for this in tree
now, so that any future migration to an in tree driver will not cause
compatiblity issues.

There two things done in this patch,
1) Existing device tree entry 'qcom,ath10k-calibration-data' carries
not only calibration data, it carries board specific data too.
So, make appropriate update in doc.
2) ipq4019 wifi needs new devie tree entry to carry calibration
data alone (called pre cal data, it doesn't include any other info).
Using 'qcom,ath10k-calibration-data' for ipq4019 would alter
the purpose of it. Hence, add new device tree entry called
'qcom,ath10k-pre-calibration-data' to carry only pre calibration data.
