6.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Max Filippov <jcmvbkbc@xxxxxxxxx>

[ Upstream commit 494e87ffa0159b3f879694a9231089707792a44d ]

When variant FSF is set, XCHAL_HAVE_DIV32 is not defined. Add default
definition for that macro to prevent build warnings:

arch/xtensa/lib/divsi3.S:9:5: warning: "XCHAL_HAVE_DIV32" is not defined, evaluates to 0 [-Wundef]
    9 | #if XCHAL_HAVE_DIV32
arch/xtensa/lib/modsi3.S:9:5: warning: "XCHAL_HAVE_DIV32" is not defined, evaluates to 0 [-Wundef]
    9 | #if XCHAL_HAVE_DIV32
