xtensa: backport fix for PR target/90922
Stack pointer adjustment code in prologue missed a case of no
callee-saved registers and a stack frame size bigger than 128 bytes.
Handle that case.
This fixes the following gcc tests with call0 ABI:
gcc.c-torture/execute/stdarg-2.c
gcc.dg/torture/pr55882.c
gcc.dg/torture/pr57569.c

* config/xtensa/xtensa.c (xtensa_expand_prologue): Add stack

stack frame bigger than 128 bytes.
