[PATCH 3/4] tests/tcg/xtensa: tidy test linker script

[Max Filippov]

Drop MEMORY clause and related size definitions and output section
region specifications. Drop .rodata output section as the tests don't
use it. Add DATA_SEGMENT_ALIGN/DATA_SEGMENT_END around .data and .bss to
let the linker make an RW segment for data. Reserve 1M for stack instead
of almost 128M.
