nds32: lds: reduce gap of flash
- Before the change was made, the "__ro_end" was at 00013520h.
We change to 00012760h.
- Rename "CONFIG_IT83XX_ILM_BLOCK_SIZE" to "IT83XX_ILM_BLOCK_SIZE"
this is because we don't support reconfiguration at board-level.
- Put some task functions into "__ram_code" section to
fill the gap and improving performance of code-fetch.
