[PATCH v2] ARM: dts: aspeed: Update reserved memory nodes for zaius and witherspoon

[Cyril Bur]

Zaius platform doesn't use VGA so don't reserve that memory

Signed-off-by: Cyril Bur <cyrilbur at gmail.com>

v2: Drop reserving the framebuffer on Zaius
    Both platforms have 1GB not 512MB - adjust numbers
    Add comment requested by Joel.
