arm64: dts: rockchip: fix num-channels property of wolfvision pf5 mic
[ Upstream commit 11d07966c83f5eccf6b927cb32862aef58488e23 ]
The Rockchip RK3568 PDM block always considers stereo inputs. Therefore,
the number of channels must be always an even number, even if a single
mono microphone is attached.
