xtensa: disable MMU initialization option on MMUv2 cores
MMU initialization option is currently ignored on MMUv2 cores, but it is used in Kconfig to select kernel load and start addresses. This choice is not available for MMUv2 cores as they have hardwired TLB entries. Disable MMU initialization option for known MMUv2 cores so that they get correct kernel load/start address by default. This fixes the default allmodconfig build. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>
