Revert "OF: base: match each node compatible against all given matches first"

Revert "OF: base: match each node compatible against all given matches first"

This reverts commit 105353145eafb3ea919f5cdeb652a9d8f270228e.
Stephen Chivers reported this is broken as we will get a match
entry '.type = "serial"' instead of the '.compatible = "ns16550"'
in the following scenario:
	serial0: serial@4500 {
		compatible = "fsl,ns16550", "ns16550";
	}

	struct of_device_id of_platform_serial_table[] = {
		{ .compatible = "ns8250",   .data = (void *)PORT_8250, },
		{ .compatible = "ns16450",  .data = (void *)PORT_16450, },
		{ .compatible = "ns16550a", .data = (void *)PORT_16550A, },
		{ .compatible = "ns16550",  .data = (void *)PORT_16550, },
		{ .compatible = "ns16750",  .data = (void *)PORT_16750, },
		{ .compatible = "ns16850",  .data = (void *)PORT_16850, },
		...
		{ .type = "serial",         .data = (void *)PORT_UNKNOWN, },
		{ /* end of list */ },
	};

So just revert this patch, we will use another implementation to find
the best compatible match in a follow-on patch.
