system: Ensure space for panic and jump data
Ensure space is available for end of ram data. End of ram data must be
located at the very end of noinit ram. This currently includes
panic_data followed by jump_data.
This is being enforced with linker asserts and build asserts rather
than allocating the space directly so RAM utiliztion reports are still
relevant.
Introduce PLATFORM_EC_PRESERVED_END_OF_RAM_SIZE config option and
default it to 1KB. This can be adjusted on boards that are
constrained.
