Vincent Palatin cca794d2fe pd: dingdong/hoho: Enable flash write-protection ...

These USB type-C accessories don't have a write-protect GPIO.
Add a configure flag (CONFIG_WP_ALWAYS) to force the flash
write-protection on the dongles.

Also set the read protection (by elevating RDP to level 1),
so trying to unprotect the flash will trigger a full erase.

BRANCH=samus
BUG=chrome-os-partner:35088
TEST=boot Hoho,
check the flash OBR and WRPR registers:
"rw 0x4002201c" / "rw 0x40022020"
and the option bytes write-protect bits: "rw 0x1FFFF808"
dump the logical state with "flashinfo" command.
> rw 0x4002201c
read 0x40022020 = 0xffff0002
> rw 0x40022020
read 0x40022020 = 0xffff0000
> rw 0x1FFFF808
read 0x1ffff808 = 0xff00ff00
