ARM: 6435/1: Fix HWCAP_TLS flag for ARM11MPCore/Cortex-A9

Commit 14eff181 added proper
detection for ARM11MPCore/Cortex-A9 instead of detecting them
as ARMv7. However, it was missing the HWCAP_TLS flags.

HWCAP_TLS is needed if support for earlier ARMv6 is compiled
into the same kernel. Without HWCAP_TLS flags the userspace
won't work unless nosmp is specified:
