mediatek: remove loglevel in bootargs

`loglevel=8` causes the kernel to output all logs, including debug logs, at boot time

It is enabled by default on the upstream eval board because it is aimed at developer debugging.

Most devices reference the eval board directly without modification, and the debug log should be hidden at release
