[PATCH 4.14 19/25] nios2: Make NIOS2_DTB_SOURCE_BOOL depend on !COMPILE_TEST

commit 4a089e95b4d6bb625044d47aed0c442a8f7bd093 upstream.

nios2:allmodconfig builds fail with

make[1]: *** No rule to make target 'arch/nios2/boot/dts/""',
needed by 'arch/nios2/boot/dts/built-in.a'. Stop.
make: [Makefile:1868: arch/nios2/boot/dts] Error 2 (ignored)

This is seen with compile tests since those enable NIOS2_DTB_SOURCE_BOOL,
which in turn enables NIOS2_DTB_SOURCE. This causes the build error
because the default value for NIOS2_DTB_SOURCE is an empty string.
Disable NIOS2_DTB_SOURCE_BOOL for compile tests to avoid the error.
