[PATCH v2 2/8] drm/amd/pm: Add ASIC independent throttle bits

[Graham Sider]

Add new defines for thermal throttle status bits which are ASIC
independent. This bit field will be visible to userspace via
gpu_metrics alongside the previous ASIC dependent bit fields. Seperated
into four 16-bit "types": power throttlers, current throttlers,
temperature, other. Also added extra defines new to v2 applicable to
renoir, namely PROCHOT and EDC bits.

Defined macro smu_u64_throttler_bit which is used instead of
__assign_bit + test_bit from previous patch revision due to upgrading to
64-bit field.
