[PATCH 5.10 11/29] mt76: mt7615: fix rdd mcu cmd endianness

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

From: Lorenzo Bianconi <lorenzo@kernel.org>

[ Upstream commit 0211c282bc8aaa15343aadbc6e23043e7057f77d ]

Similar to mt7915 driver, fix mt7615 radar mcu command endianness

Fixes: 2ce73efe0f8e5 ("mt76: mt7615: initialize radar specs from host driver")
Fixes: 70911d9638069 ("mt76: mt7615: add radar pattern test knob to debugfs")
