devicetree: Remove DT_SRAM_{BASE_ADDRESS,SIZE}, use CONFIG_* versions

Browse source 
The SRAM address and size are currently available as both
DT_SRAM_{BASE_ADDRESS,SIZE} and as CONFIG_SRAM_{BASE_ADDRESS,SIZE} (via
the Kconfig preprocessor).

Use the CONFIG_SRAM_* versions everywhere, and remove generation of the
DT_SRAM_* versions from gen_defines.py.

The Kconfig symbols currently depend on 'ARC || ARM || NIOS2 || X86'.
Not sure why, so I removed it.

It looks like no configuration files set CONFIG_SRAM_* at the moment, so
another option might be to use the DT_* symbols everywhere instead. Some
Kconfig.defconfig.series files add defaults to them though.

Also improve the help texts for CONFIG_SRAM_* to say that they normally
come from devicetree rather than configuration files.
