arm64: dts: allwinner: h5: Fix PMU compatible

commit 4ae7a3c3d7d31260f690d8d658f0365f3eca67a2 upstream.

The commit c35a516a4618 ("arm64: dts: allwinner: H5: Add PMU node")
introduced support for the PMU found on the Allwinner H5. However, the
binding only allows for a single compatible, while the patch was adding
two.

Make sure we follow the binding.
