It makes much more sense for the Root Object to be create within the
board and passed where required. Creating it in the Simulator class is
not required.
For this to work the signuature of the `_pre_instantiate` function in
`AbstractBoard` has been updated to return the Root object.
This commit contains the rest of the base 2 vs base 10 cache/memory
size clarifications. It also changes the warning message to use
warn(). With these changes, the warning message should now no
longer show up during a fresh compilation of gem5.

As X86 and RISCV are relying on a Table Walker cache, we
change their stdlib configs to use the newly defined
PrivateL1PrivateL2WalkCacheHierarchy

* stdlib,configs,tests: Remove `Resource` class use
This class is deprecated, but was still used in various example
configuration scriots and tests. This patch replaces it with the
`obtain_resource` function.

* configs: Remove `CustomDiskImageResource` use
The class is deprecated but was still used in the SPEC example scripts.
This patch replaces it with the `DiskImageResource` class.

* configs,tests: Remove `CustomResource` use
This class is deprecated but was still used in example scripts and
mentioned, incorrectly, in comments in the pyunit tests. This patch
removes these.

* stdlib: Remove '\' in Workload docstring example
This example shows how to use the Workload. The backslash is not correct Python and would fail if used in this way.

The main restriction with this design is it results in one ISA target
per board. The ISA is declared per core. To make the design simpler it's
assumed a Processor (a collection of cores) are all of the same ISA. As
each board has one processor, this also means a board is typically tied
to one ISA per simulation.
In order to remain backwards compatible and maintain the standard
library APIs, this patch adds a `--main-isa` parameter which will
determine what `gem5.runtime.get_runtime_isa` returns in cases where
mutliple ISAs are compiled in. When setting the ISA in a simulation (via
the Processor or Cores), the user may, as before, choose not to and, in
this case, the `gem5.runtime.get_runtime_isa` function is used.
The `gem5.runtime.get_runtime_isa` function is an intermediate step
which should be removed in future versions of gem5 (users should specify
precisely what ISA they want via configuration scripts). For this reason
it throws a warning when used and should not be heavily relied upon. It
is deprecated.
