[PATCH] sh: Fix built-in DTB build with generic rule

[Florian Fuchs]

Commit 21bcc49974c2 ("sh: Migrate to the generic rule for built-in DTB")
selected GENERIC_BUILTIN_DTB and renamed the Kconfig symbols, but left
arch/sh/boot/dts/Makefile using the old obj-y form. So convert them as
well, to fix the build error when using CONFIG_BUILTIN_DTB.

The fix is the same like at other places like openrisc or nios.
Without that, the build fails, when building with builtin device tree:
CONFIG_BUILTIN_DTB=y
CONFIG_BUILTIN_DTB_NAME="j2_mimas_v2"
with an error like:
.builtin-dtbs.S:6: Error: file not found: arch/sh/boot/dts/j2_mimas_v2.dtb
