[PATCH 1/1] lmb: always enforce CONFIG_LMB

[PATCH 1/1] lmb: always enforce CONFIG_LMB

[Heinrich Schuchardt]

We don't have any platforms left that build without LMB.
Configuring something useful without LMB is difficult.

Always enforce CONFIG_LMB=y.
Move selecting CONFIG_ARCH_MISC_INIT to the `config PPC` definition.

We have a handful of platforms that don't enable LMB:
$ ./tools/qconfig.py -f ~LMB
