ARM: 6207/1: Replace CONFIG_HAS_TLS_REG with HWCAP_TLS and check for it on V6
The TLS register is only available on ARM1136 r1p0 and later. Set HWCAP_TLS flags if hardware TLS is available and test for it if CONFIG_CPU_32v6K is not set for V6. Note that we set the TLS instruction in __kuser_get_tls dynamically as suggested by Jamie Lokier <jamie@shareable.org>. Also the __switch_to code is optimized out in most cases as suggested by Nicolas Pitre <nico@fluxnic.net>.
