[PATCH 30/77] hw/riscv: Allow 64 bit access to SiFive CLINT |

Commit 5d971f9e672507210e77d020d89e0e89165c8fc9
"memory: Revert "memory: accept mismatching sizes in
memory_region_access_valid"" broke most RISC-V boards as they do 64 bit
accesses to the CLINT and QEMU would trigger a fault. Fix this failure
by allowing 8 byte accesses.
