powerpc: Remove inaccessible CMDLINE default

Browse source 
Since commit cbe46bd4f5 ("powerpc: remove CONFIG_CMDLINE #ifdef mess")
CONFIG_CMDLINE has always had a value regardless of CONFIG_CMDLINE_BOOL.

For example:

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

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

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

Remove CONFIG_CMDLINE_BOOL and the inaccessible default.
