dm: core: fix dev_read_alias_highest_id() without libfdt

If CONFIG_DM_DEV_READ_INLINE is set, dev_read_alias_highest_id() calls
libfdt_get_highest_id(). But this function is only available if we have
libfdt compiled in. If its not available return -1, which matches the
return code for no alias found.

This fixes the following error on omapl138_lcdk:
arm-linux-gnueabi-ld.bfd: drivers/built-in.o: in function `dev_read_alias_highest_id':
/home/mw/repo/u-boot/include/dm/read.h:986: undefined reference to `fdtdec_get_alias_highest_id'
