However, according to the privileged spec, interrupt causes >= 16 are defined for platform use. This limitation prevents to fully utilize the available local interrupt sources. Additionally, the interrupt number used on RISC-V are sparse, with only interrupt numbers 1, 5 and 9 (plus Sscofpmf or T-Head's PMU interrupt) being currently used for supervisor mode. Switch to using irq_domain_create_tree() to create the radix tree map, so a larger number of hardware interrupts can be handled.

Instead of diverting the bits and register reserved for future standard, a set of custom registers is added. Hence, we may consider it as a CPU feature rather than an erratum. T-Head cores need to append "xtheadpmu" to the riscv,isa-extensions for each cpu node in device tree, and enable CONFIG_THEAD_CUSTOM_PMU for proper functioning as of this commit.
