v1/v2:
There is only the first patch: RISC-V: Enable cbo.clean/flush in usermode,
which mainly removes the enabling of cbo.inval in user mode.

v3:
Add the functionality of Expose Zicbom and selftests for Zicbom.

v4:
Modify the order of macros, The test_no_cbo_inval function is added
separately.

v5:
1. Modify the order of RISCV_HWPROBE_KEY_ZICBOM_BLOCK_SIZE in hwprobe.rst
2. "TEST_NO_ZICBOINVAL" -> "TEST_NO_CBO_INVAL"

v6:
Change hwprobe_ext0_has's second param to u64.

v7:
Rebase to the latest code of linux-next.
