Subject: [PATCH 01/16] xtensa: FSF: define XCHAL_HAVE_DIV32

When variant FSF is set, XCHAL_HAVE_DIV32 is not defined,
so add the define for FSF 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

Fixes: 173d6681380a ("xtensa: remove extra header files")
