[PATCH v2 1/1] riscv: define a cache line size for the generic CPU

[Heinrich Schuchardt]

The USB 3.0 driver xhci-mem.c requires CONFIG_SYS_CACHELINE_SIZE to be set.

Define the cache line size for QEMU on RISC-V to be 64 bytes.

        Select SYS_CACHE_SHIFT_6 for GENERIC_RISCV and not for
        TARGET_QEMU_VIRT (as suggested by Bin)
