linker: intel_s1000: Remove limits on code and data sections
All text, data and bss sections are all mapped to the same physical memory (SRAM). This patch removes the individual section limits and defines a common limit for the sum of text, data and bss sections. This would make it more flexible for application developers. Fixes #11268.
