esp8266/esp8266_common.ld: Put .text of more libs into .irom0.text .

pfalcon · pfalcon · commit 964bf935a394 · 2017-11-14T09:24:33.000+02:00
Recent vendor SDKs ship libs with code in .text section, which previously
was going into .irom0.text. Adjust the linker script to route these
sections back to iROM (follows upstream change).
