crypto: powerpc/poly1305 - add depends on BROKEN for now

Browse Source 
As discussed in the thread containing
https://lore.kernel.org/linux-crypto/20250510053308.GB505731@sol/, the
Power10-optimized Poly1305 code is currently not safe to call in softirq
context.  Disable it for now.  It can be re-enabled once it is fixed.

Fixes: ba8f8624fd ("crypto: poly1305-p10 - Glue code for optmized Poly1305 implementation for ppc64le")
