[ Upstream commit 867050247e295cf20fce046a92a7e6491fcfe066 ]

xtensa frame size is larger than the frame size for almost all other
architectures. This results in more than 50 "the frame size of <n> is
larger than 1024 bytes" errors when trying to build xtensa:allmodconfig.

Increase frame size for xtensa to 1536 bytes to avoid compile errors due
to frame size limits.
