[meta-freescale] blacklist evbug or remove it from the kernel config

[Carlos Rafael Giani]

Hello,

evbug is enabled by default with newer kernels. This is highly annoying. 
It prints a debug message for every single HID activity. Mouse movement, 
key presses etc.
It can slow down the system.

evbug is blacklisted in Ubuntu's modprobe config. I think it is wise to 
do the same in meta-fsl-arm . Blacklisting is probably more effective, 
since otherwise, the configurations of all kernels in meta-fsl-arm and 
meta-fsl-arm-extra have to be modified.

cheers
