[coreboot] [patch] fix NCT6776F support in superiotool

[Florian Zumbiehl]

The current code exits config mode of the NCT6776F immediately after
detection, so the register dump shows all 0xffs. This patch adds code to
re-enter config mode for the register dump so that the register contents
can be read.
