config: def configs for p50x updated
some modules are important to pass lge logo.
So modules (wifi and scsi excluded) are now build into kernel, so we can't forget to include them.
Kernel logo is enabled to see the switch from kernel loading to rom boot.

Now kernel is booting. Massstorage and adb are recognized by pc.
Than it reboots into recovery.
