[ Upstream commit 705d2fde94b23cd76efbeedde643ffa7c32fac7f ]
When loading FW from file add block size checks to ensure a
corrupted FW file will not cause the driver to write outside
the device memory.

Driver fails to load FW for sparrow D0 devices in some cases.
Fix this by returning correct value from wil_fw_verify_file_exists
when D0 FW file is not detected for any reason.

Driver may be used in platforms where some use sparrow cards while
other use sparrow-plus cards, where different FW image is needed.
Add the capability to load dedicated FW image in case sparrow-plus
card is detected and fallback to default image if such does not exist.

Currently the FW version is taken from the sw_version field
of the FW ready event. This version is based on internal
version control revision and it is difficult to map to actual
FW version.
Fix this by using the actual FW version stored in the FW file
header record.

When driver is loaded, extract a capabilities record
from the FW file. This record contains bits indicating
which optional features are supported by this FW.
The driver can use this information to determine
which functionality to support and/or expose to user
space.
The extraction is done before wiphy structure is
registered, because the capabilities can affect
information published by the this structure.

Replace macros like "R", "W", "S", "C", defined multiple times,
with inline functions "wil_[rwsc]".
Use "readl" and "writel" instead of "ioread32" and "iowrite32"
since it is granted that memory transactions are used,
not port ones like IN/OUT

Introduce boot loader. Instead of the operational firmware,
very small boot loader is burned to the on-board flash. Boot loader
initializes hardware upon reset, and prepares for low power mode.
Boot loader reports MAC address and detects radio chip connected.
Driver loads firmware only when bringing up interface. All information
required to set up network interface, most important is MAC address,
reported by the boot loader
The firmware composed of 2 files:
- wil6210.fw - firmware itself (compiled code + data)
- wil6210.board - board file (various board and radio dependent
calibrations and parameters)

In some compilation environments, result of pointer arithmetic interpreted as int
while in others it is long int. Force conversion to long.

There is no need to obtain physical device through
wil->pdev->dev path, as it is done by this macro.
The same device already stored as wiphy's device, thus
wil_to_dev() returns the same device as wil_to_pcie_dev()
Remove unnecessary macros, this allows to drop dependency
by pci.h in the firmware download code.

Firmware download implemented but is still experimental feature;
flag controlling it added, no_fw_load. It is true by default,
use no_fw_load=N to activate feature.
Reset flows also got some adjustment for the fw download to work
