media: amphion: Fix VPU core alias name

commit f033c87fda47e272bb4f75dc7b03677261d91158 upstream.

Starting with commit f6038de293f2 ("arm64: dts: imx8qm: Fix VPU core
alias name") the alias for VPU cores uses dashes instead of underscores.
Adjust the alias stem accordingly. Fixes the errors:
amphion-vpu-core 2d040000.vpu-core: can't get vpu core id
amphion-vpu-core 2d050000.vpu-core: can't get vpu core id

Fixes: f6038de293f2 ("arm64: dts: imx8qm: Fix VPU core alias name")
