To generalize manifest file for StandaloneMm for FVP,
organize this manifest file by separating:
* stmm_common.dtsi
- collection of macros to used by {plat_}stmm_*.dts(i) files.
* stmm_dev_region.dtsi
- device region template for StandaloneMm.
- If some environment don't required it, it can be excluded in
by not defining STMM_XXX macro.
* stmm_mem_region.dtsi
- memory region template for StandaloneMm.
* stmm_template.dts
- StandaloneMm manifest template defining common root node
information.
* fvp_stmm_{xxx}_manifest.dts
- Main StandaloneMm manifest file.
- According to environment, defines proper STMM_XXX value
to define device/memory region.
- device region can be excluded by not defining some STMM_XXX macro.
This is useful to define new StandaloneMm manifest
in different environments.
