fdtdec: Add declaration for get_next_memory_node() helper
Add get_next_memory_node() function declaration to fdtdec.h to support
iterating through multiple memory nodes in device tree. This function
is used to enumerate memory banks when the system has non-contiguous
or multiple memory regions defined with device_type = "memory".
The function implementation already exists in lib/fdtdec.c (lines
1298-1305) but was missing the public declaration in the header file.
This patch adds the declaration and includes dm/ofnode_decl.h for the
ofnode type definition.
This is needed for platforms that require early memory enumeration
before standard fdtdec_setup_memory_banksize() is called, particularly
for dynamic MMU page table size calculation based on actual DRAM
configuration.
