Kconfig: Add a default cache line size for RISC-V
The RISC-V ISA profile RVA23U64 requires extension Zic64b (Cache blocks
must be 64 bytes in size, naturally aligned in the address space).
Some RISC-V platforms do not define the d-cache line size through SYS_CACHE_SHIFT_n.
Set a default value of 64 bytes for such cases.
