BlackMark b7d082ff11 pureboot: correct the 1284P deployment profiles in the README
The deployment section claimed the 1284P has no standalone profile, runs
BOOTSZ = 512 words always, and self-updates with no fuse change, reset
landing at 0x1f800 — internally contradictory (a 512-word section starts
at 0x1fc00, and the section holding both 1 KiB slots is 1024 words) and
contradicted by update_preflight, which refuses a self-update unless the
boot section covers two slots. The text described a 512-byte-slot
geometry this chip's loader cannot have. In truth the 328P profile table
maps onto the 1284P doubled: standalone = 512 words (the smallest
section is exactly the 1 KiB slot, reset at the loader base), self-update
= 1024 words with the loader-first reset walking the staging slot.
