  riscv: move sifive_l2_cache.c to drivers/soc (2019-12-20 03:40:24 -0800)

----------------------------------------------------------------
RISC-V updates for v5.5-rc3

Several fixes, and one cleanup, for RISC-V.

Fixes:

- Fix an error in a Kconfig file that resulted in an undefined Kconfig
  option "CONFIG_CONFIG_MMU"

- Fix undefined Kconfig option "CONFIG_CONFIG_MMU"

- Fix scratch register clearing in M-mode (affects nommu users)

- Fix a mismerge on my part that broke the build for
  CONFIG_SPARSEMEM_VMEMMAP users

Cleanups:

- Move SiFive L2 cache-related code to drivers/soc, per request
