board: phytec: phycore-imx93: Add 2GB LPDDR4X RAM timings

The phyCORE-i.MX 93 is available with a 1GB ram chip or a 2GB ram chip.
Add the ram timings for the 2GB chip, in form of a diff compared
to the existing LPDDR4X 1GB timings. With that, the SPL can select the
appropriate timings at startup.
Update also the 1GB ram timings with new version of the DDR Tool.
