target/xtensa: xtfpga: provide default memory sizes

Provide default RAM sizes for all XTFPGA boards, so that when started without -m option they do the right thing.

Signed-off-by Max Filippov <[email protected]>

Reviewed-by Philippe Mathieu-Daudé <[email protected]>

---
Changes v2->v3:
- add XTFPGA_MMU_RESERVED_MEMORY_SIZE definition and express Xilinx board memory sizes using it as suggested by Philippe;

Changes v1->v2:
- fix memory sizes for ml605 and kc705 with MMU
