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

[J. Neuschäfer via B4 Relay]

From: "J. Neuschäfer" <j.ne@posteo.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`.

This fits on a single line (many more below)

Even when it wouldn't fit on a single line, having separate

    dtb-$(CONFIG_FOO) += bar1.dtb
    dtb-$(CONFIG_FOO) += bar2.dtb

lines not only makes it a little bit shorter, but avoids the churn of
adding a backslash to the previous line when adding new entries.

Sounds good, I'll do that for v2.
