RISC-V updates for v5.5-rc5

Several fixes for RISC-V:

- Fix function graph trace support

- Prefix the CSR IRQ_* macro names with "RV_", to avoid collisions
with macros elsewhere in the Linux kernel tree named "IRQ_TIMER"

- Use __pa_symbol() when computing the physical address of a kernel
symbol, rather than __pa()

- Mark the RISC-V port as supporting GCOV

One DT addition:

- Describe the L2 cache controller in the FU540 DT file

One documentation update:

- Add patch acceptance guideline documentation
