arm64: dts: ti: k3-am62a7-sk: Fix DDR size to full 4GB
[ Upstream commit a1bc0d6084dba8a31831c65318a8a8e46f00906f ]
All revisions of AM62A7-SK board have 4GB LPDDR4 Micron
MT53E2G32D4DE-046 AUT:B memory. Commit 38c4a08c820c ("arm64: dts: ti:
Add support for AM62A7-SK") enabled just 2GB due to a schematics error
in early revision of the board. Fix it by enabling full 4GB available on
the platform.
