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.

      This option enables DRAM data scramble, which can prevent DRAM data from
      being hacked.
