Renesas R-Car V4H (r8a779g0) has PCIe controller, and it requires
specific firmware downloading. The firmware is now available via
linux-firmware.git repository, drop the documentation about how
to obtain the firmware.

-=================================================
-Firmware of PCIe controller for Renesas R-Car V4H
-=================================================
-
-Renesas R-Car V4H (r8a779g0) has a PCIe controller, requiring a specific
-firmware download during startup.
-
-However, Renesas currently cannot distribute the firmware free of charge.
-
-The firmware file "104_PCIe_fw_addr_data_ver1.05.txt" (note that the file name
-might be different between different datasheet revisions) can be found in the
-datasheet encoded as text, and as such, the file's content must be converted
-back to binary form. This can be achieved using the following example script:
-
-.. code-block:: sh
-
-	$ awk '/^\s*0x[0-9A-Fa-f]{4}\s+0x[0-9A-Fa-f]{4}/ { print substr($2,5,2) substr($2,3,2) }' \
-		104_PCIe_fw_addr_data_ver1.05.txt | \
-			xxd -p -r > rcar_gen4_pcie.bin
-
-Once the text content has been converted into a binary firmware file, verify
-its checksum as follows:
-
-.. code-block:: sh
-
-	$ sha1sum rcar_gen4_pcie.bin
-	1d0bd4b189b4eb009f5d564b1f93a79112994945  rcar_gen4_pcie.bin
-
-The resulting binary file called "rcar_gen4_pcie.bin" should be placed in the
-"/lib/firmware" directory before the driver runs.

Applied, thanks!
