meta-ampere: remove GPIO fault check
This commit removes scripts to check GPIO fault as they poll GPIOs every
0.25s. Better solution needs to be found for this feature.

-# This script monitors S0/S1 GPIO fault and detects errors from CPUs
-#
-# So far, there is no specification describes the behavior of LED when an error (a pattern is detected) occurs.
-# So when detecting a pattern, we simply set the gpio fault flag and turn on the SYS LED.
-#
-# The Parttern will in the format:
-# <minor_byte> <quite_gap_1second> <major_byte> <stop_condition_low_for_3seconds>
-#
-# Ex: pattern minor_byte=0x03, major_byte=0x02, you will see the waveform like
-# _1010100...(quite gap, low for 1 second)..0111111111000000000111111111110000000000...(stop condition, low for 3 seconds)..
