soc/intel/mtl: Change default for debug consent from 3 to 6

USB DBC is very helpful for SoC debug. TraceHub needs to be enabled in
coreboot if debug consent == 2 or 4. Debug consent == 6 enables USB DBC without TraceHub enabled.

This patch updates the Kconfig help text to meet PlatformDebugOption in
MTL and changes debug consent to 6 in default to provide basic SoC
debug capability.

TEST=Boot to OS on screebo and DBC connection is OK.
