arm: mach-k3: Fix phandle corruption in fdt fixup

Fix phandle corruption in fdt_fixup_reserved_memory()

The original implementation used a delete/recreate approach:
- Find existing reserved memory node (e.g. tfa@80000000)
- Delete the entire node with fdt_del_node()
- Create new node with fdtdec_add_reserved_memory()

This worked fine for ATF and OPTEE nodes because no other device tree
nodes reference them via phandles but other nodes example DM are
referenced by R5 nodes.

If these nodes are deleted and recreated, it will not have any phandle
property but the nodes referencing it will still contain the old
phandle, causing initialization to fail.

Update nodes in-place instead of delete/recreate to update only the
"reg" property using fdt_setprop().
