Enable more options required as dependencies.

(p/ directory version)

When verifying the android-base and android-recommended configurations,
it is useful to start from as minimal a kernel config as possible. The
most minimal config is "allnoconfig".

However, the "allnoconfig" experiment highlights a design problem with
these kernel config fragments. The 'depends' for the options we want to
turn on won't be turned on if the defconfig used as the first parameter
to scripts/kconfig/merge_config.sh forcibly turned them off, even if the
options were 'default y' or 'default m'.

So, rather than relying on somebody running the merge_config.sh having
the 'depends' set favorably for dependent options, explicitly define all
of the dependencies with =y. When testing with an "allnoconfig", which
is a worst-case scenario, all of the 'base' and 'recommended' options
are now turned on correctly.

android-base.cfg:
