    dom0less: Remove redundant magic check in 'check_partial_fdt()'
    
    The function 'check_partial_fdt()' performs an explicit check for the FDT
    magic number (FDT_MAGIC) before calling 'fdt_check_header(). This check is
    redundant, because 'fdt_check_header()' includes checking the magic number.
    
    Remove the redundant check to simplify the code and rely on the library
    function to perform header validation.
