drivers/perf: hisi: Add tt_core_deprecated for compatibility

Previously tt_core is defined as config1:0-7 which may not cover all
the CPUs sharing L3C on platforms with more than 8 CPUs in a L3C. In
order to support such platforms extend tt_core to 16 bits, since no
spare space in config1, tt_core was moved to config2:0-15.

Though linux expects the users to retrieve the control encoding from
sysfs first for each option, it's possible if user doesn't follow
this and hardcoded tt_core in config1. So add an option
tt_core_deprecated for config1:0-7 for backward compatibility.
