[PATCH] powerpc: Remove inaccessible CMDLINE default

From: Chris Packham <chris.packham@alliedtelesis.co.nz>
Date: 2019-08-02 05:02:43

Since commit cbe46bd4f510 ("powerpc: remove CONFIG_CMDLINE #ifdef mess")
CONFIG_CMDLINE has always had a value regardless of CONNIG_CMDLINE_BOOL.

For example:

 $ make ARCH=powerpc defconfig
 $ cat .config
 # CONFIG_CMDLINE_BOOL is not set
 CONFIG_CMDLINE=""

When enabling CONNIG_CMDLINE_BOOL this value is kept making the 'default
"..." if CONNIG_CMDLINE_BOOL' ineffective.

 $ ./scripts/config --enable CONFIG_CMDLINE_BOOL
 $ cat .config
 CONFIG_CMDLINE_BOOL=y
 CONFIG_CMDLINE=""

Additionally all the in-tree powerpc defconfigs that set
CONFIG_CMDLINE_BOOL=y also set CONFIG_CMDLINE to something else. For
these reasons remove the inaccessible default.

I think we could also get rid of CMDLINE_BOOL totally and use CMDLINE !=

The only reason I can see to keep CMDLINE_BOOL is that it hides the
text input for CMDLINE which seems to be a pattern in Kconfig. Happy to
remove it if that's the consensus. 

I'll wait for the dust to settle on my other patch before sending a v2
of this one.
