mediatek: filogic: comfast cf-wa933: clean up legacy device definitions

Remove the fixed memory node and console bootargs override, relying on
the bootloader to supply the memory map and command line. Drop the DTB
padding and explicit kernel/FDT load addresses so the image definitions
use the Filogic defaults. I have boot-tested the standard target with
these settings removed. Both existing variants inherit the changes.

Remove the redundant crypto status override. The inherited SoC node
has no status property, which leaves it available; this does not disable
the EIP-97 engine.

Remove the CPU port's user-facing label while keeping its Ethernet link
and switch topology.

Remove the explicit SPI address and size cell properties.

Drop the standard target's 64M display suffix, which describes its UBI
region size rather than a different NAND device. Keep its 64 MiB image
limit. Add cf-wa933 as a supported-device alias for the standard target,
matching the short compatibility alias used by the CF-WR632AX.

Keep both existing targets and their NMBM partition maps intact.
