xtensa: fix noMMU build on cores with MMU

Browse Source 
commit 4b3e6f2ef3 upstream.

Commit bf15f86b34 ("xtensa: initialize MMU before jumping to reset
vector") calls MMU management functions even when CONFIG_MMU is not
selected. That breaks noMMU build on cores with MMU.

Don't manage MMU when CONFIG_MMU is not selected.
