	Some T-Head based processors, for example the Sophgo SG2044, have a JTLB errata that requires special handling of certain TLB maintenance instructions (sfence.vma). Introduce a sbi_tlb_local_operations structure so platforms can provide custom local TLB flush implementations. Use it to implement the JTLB workaround on affected SoCs (currently Sophgo SG2044).

2024-05-09	platform: generic: thead: separate T-Head PMU Errata	Yangyu Chen
	As Guo Ren said from the kernel mailing list [1], future T-Head CPUs, including the newer versions of T-Head C908, will feature standard Sscofpmf extension. For these CPUs, T-Head's implementation of PMU Overflow Interrupts may not needed anymore. In this case, we shouldn't apply T-Head PMU for all T-Head CPUs. Thus, this patch separated T-Head PMU errata.
