[PATCH] riscv: move sifive_l2_cache.c to drivers/misc

[Christoph Hellwig <hch@lst.de>]

The sifive_l2_cache.c is in no way related to RISC-V architecture
memory management.  It is a little stub driver working around the fact
that the EDAC maintainers prefer their drivers to be structured in a
certain way that doesn't fit the SiFive SOCs.

Move the file to drivers/misc and only build it when the EDAC_SIFIVE
config option is selected.

Fixes: a967a289f169 ("RISC-V: sifive_l2_cache: Add L2 cache controller driver for SiFive SoCs")
