Subject: vgacon: Set VGA struct resource types

From: Bjorn Helgaas <bhelgaas@google.com>


[ Upstream commit c82084117f79bcae085e40da526253736a247120 ]

Set the resource type when we reserve VGA-related I/O port resources.

The resource code doesn't actually look at the type, so it inserts
resources without a type in the tree correctly even without this change.
But if we ever print a resource without a type, it looks like this:

  vga+ [??? 0x000003c0-0x000003df flags 0x0]

Setting the type means it will be printed correctly as:

  vga+ [io  0x000003c0-0x000003df]
