hathach 708c4f9fb5 bsp: document .DMADATA as uninitialised-only and drop its bogus load region ...

The section is NOLOAD and startup_CH56x.S zeroes it, so an object placed there
WITH an initialiser silently loses it: the bytes never reach the .bin and the
zero-fill runs over them, with no diagnostic from the compiler, linker or
objcopy. That is reachable by ordinary code because CFG_TUSB_MEM_SECTION is
defined to .dmadata for this family. Nothing currently relies on an initialiser
there, so this documents the contract rather than changing behaviour, and drops
the AT>FLASH load region, which is meaningless for a section that is never
loaded (the ELF now reports LMA == VMA instead of a flash address).
