[PATCH v8 3/5] riscv_cbqri: Make RESCTRL_FS available on RISC-V

[Drew Fustini]

Enough CBQRI support is now present to enable ARCH_HAS_CPU_RESCTRL.
Have RISCV_CBQRI select it so that RESCTRL_FS can be enabled on
RISC-V, and default RISCV_CBQRI to y. RISCV_ISA_SSQOSID is default n,
so this only affects kernels where the user has already opted into
Ssqosid, and on those the CBQRI support is what makes the extension
useful.

This is a separate patch so that no commit makes RESCTRL_FS selectable
before the resctrl glue it depends on exists. Enabling the resctrl
filesystem itself stays a user choice under MISC_FILESYSTEMS.
