[Buildroot] [PATCH v2 1/7] arch/xtensa: get rid of an intermediate blind kconfig option

[Max Filippov]

From: "Yann E. MORIN" <yann.morin.1998 at free.fr>

It is not needed to have an intermediate blind option, we can just
hide the prompt behind the same dependency as the non-blind symbol.

Update our qemu-xtensa defconfig acordingly (note: it was using
different values for both options, which is not possible; the blind
option was just set to the non-blind one in the .config).

Also remove an unneeded empty default for the BR2_XTENSA_OVERLAY_DIR
string option (strings are empty by default).
