riscv: export flush_icache_all to modules
This is needed by LKDTM (crash dump test module), it calls flush_icache_range(), which on RISC-V turns into flush_icache_all(). On other architectures, the actual implementation is exported, so follow that precedence and export it here too. Fixes build of CONFIG_LKDTM that fails with: ERROR: "flush_icache_all" [drivers/misc/lkdtm/lkdtm.ko] undefined!
