Update README.txt files for boards using SDCC
Modified boards/z80/z180/p112/README.txt and boards/z80/z80/z80sim/README.txt:
IMPORTANT NOTE as of 2020-4-11: Support for CONFIG_CAN_PASS_STRUCTS was removed in NuttX-9.1. This was necessary to enforce some POSIX interface compliance but also means that ALL older SDCC versions will no long build with NuttX.

2014-8-22: After some time idling away, I tried rebuilding with Windows 8,
