PS3, Line 7: Add prompt for the SCRAMBLE config
Add a prompt string for MEDIATEK_DRAM_SCRAMBLE

https://review.coreboot.org/c/coreboot/+/75815/comment/d671a4ce_cabbaab6 :
PS3, Line 9: Unexpectedly, fwserial.{project} won't override the Kconfig if the
           : Kconfig prompt is empty.
           : 
           : CONFIG MEDIATEK_DRAM_SCRAMBLE
           : 	bool
           : 
           : After adding the prompt after the previous line "bool", i.e.
           : 	bool "Enable DRAM scramble feature"
           : 
           : It works!
Make the default MEDIATEK_DRAM_SCRAMBLE value overridable by adding a
prompt string.
