[PATCH v1 3/5] arm: dts: k3-am6xx: Fix FIT image memory overlap in binman configurations

Fix memory overlaps in FIT image configurations for TI AM62x and AM64x
PHYCore and SK boards.
The overlaps occurred in two categories:
1. TI firmware stub images (tifsstub-hs, tifsstub-fs, tifsstub-gp):
These mutually exclusive firmware variants were incorrectly assigned
the same load address within FIT configurations, causing overlap
detection to fail. Adjust addresses with 64KB spacing:
- tifsstub-hs: Keep original address
- tifsstub-fs: Move to +64KB offset
- tifsstub-gp: Move to +128KB offset
2. Device tree overlay images (som-no-rtc, som-no-spi, som-no-eth):
These overlay files had insufficient spacing between load addresses,
causing actual memory overlaps. Increase spacing to 8KB boundaries
to accommodate overlay sizes safely.
An upcoming commit will validate if the memory region is overlapped
