bld.sh: update defconfig list

we renamed mid7022 to tcc88xx_ua as to indicate that it supports
more then just the mid7022, but the whole 2nd generation TCC8803
based COBY tablets.
TCCDUMP: only compiles on TCC8803 based SoCs
plat/tcc: move atheros_wifi_mac to plat-tcc
fix a set of section mismatches

Mostly caused by *_probe functions being annotated as __init, while
they are not.
tca_keypad cleanup.
