brcmfmac4330-sdio.txt is OEM, respectively even device specific[1],
nothing that would be generic enough (for all bcm4330 devices) to be
shipped by Debian's firmware packages.
On x86 systems this blob is typically provided in a UEFI variable (but not
found automatically by the kernel, so you need to copy it from the UEFI
variable to /lib/firmware). On embedded devices it needs to be provided by
the manufacturer (not Broadcom, but the OEM vendor) of your wlan card
(respectively the devboard).

[1] These blobs contain calibration data, regulatory domain settings
and similar information, which is highly specific to your exact
device. Using data from a different device would make it run out
of its specifications (getting you in trouble with FCC, ETSI,
etc.) and could even physically damage your device.
