soc/mediatek/common: Disable DRAM scramble by default
Geralt SoC does not support 'persist certain regions' across reboots.
Considering the impact of missing ramoops for debugging, set
MEDIATEK_DRAM_SCRAMBLE to default n to disable this feature in
production FW image.
BUG=b:269049451,b:278478563
TEST=emerge-geralt coreboot and confirm CONFIG_MEDIATEK_DRAM_SCRAMBLE=n
