Subject: [PATCH] powerpc: dts: Build devicetrees of enabled platforms

From: "J. Neuschäfer" <j.ne@...teo.net>

Follow the same approach as other architectures such as Arm or RISC-V,
and build devicetrees based on platforms selected in Kconfig. This makes
it unnecessary to use CONFIG_OF_ALL_DTBS on PowerPC in order to build
DTB files.

This makes it easier to use other build and test infrastructure such as
`make dtbs_check`, and is a first step towards generating FIT images
that include all the relevant DTBs with `make image.fit`.
