Subject: [PATCH] arm64: tegra: Wire up WiFi on Jetson TX1 module

P2180 modules have WiFi in form of BCM4354 chip, and kernel driver
supports this one, so enable it for all users. The necessary calibration
file can be obtained from Jetson Linux Archive. nvram.txt file is
located in "Driver Package (BSP)" in
nv_tegra/l4t_deb_packages/nvidia-l4t-firmware_<version>_arm64.deb
archive. The rest of necessary blobs can be obtained from official
Linux Firmware repository or (newer ones) from Infineon
ifx-linux-firmware repository (look in older releases).
