Daniel Leung e444cc9fb9 xtensa: mmu: always map data TLB for VECBASE
This adds code to always map data TLB for VECBASE so that
we would be dealing with fewer data TLB misses during
exception handling. With VECBASE always mapped, there is
no need to pre-load anymore.

The Zephyr Project is a scalable real-time operating system (RTOS) supporting
multiple hardware architectures, optimized for resource constrained devices,
and built with security in mind.

The Zephyr OS is based on a small-footprint kernel designed for use on
resource-constrained systems: from simple embedded environmental sensors and
LED wearables to sophisticated smart watches and IoT wireless gateways.

The Zephyr kernel supports multiple architectures, including ARM (Cortex-A,
Cortex-R, Cortex-M), Intel x86, ARC, Nios II, Tensilica Xtensa, and RISC-V,
SPARC, MIPS, and a large number of `supported boards`_.
