The mv64x60 EDAC driver depends on CONFIG_MV64X60. But that symbol is
not user-selectable, and the last code that selected it was removed
with the C2K board support in 2018, see:

  92c8c16f3457 ("powerpc/embedded6xx: Remove C2K board support")

That means the driver is now dead code, so remove it.

This driver supports Intel client SoC with integrated memory controller
using In-Band ECC(IBECC). The memory correctable and uncorrectable errors
are reported via NMIs. The driver handles the NMIs and decodes the memory
error address to platform specific address. The first IBECC-supported SoC
is Elkhart Lake.

The Amazon's Annapurna Labs Memory Controller EDAC supports ECC capability
for error detection and correction (Single bit error correction, Double
detection). This driver introduces EDAC driver for that capability.

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.

This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.

There are a variety of indentation styles found.

  a) 4 spaces + '---help---'
  b) 7 spaces + '---help---'
  c) 8 spaces + '---help---'
  d) 1 space + 1 tab + '---help---'
  e) 1 tab + '---help---'    (correct indentation)
  f) 1 tab + 1 space + '---help---'
  g) 1 tab + 2 spaces + '---help---'

In order to convert all of them to 1 tab + 'help', I ran the
following commend:

  $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

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/soc and add a Kconfig option for it, as well
as the whole drivers/soc boilerplate for CONFIG_SOC_SIFIVE.
