MIPS: Malta: Fix keyboard resource preventing i8042 driver from registering

commit bf557059 upstream.

MIPS Malta platform code registers the PCI southbridge legacy port I/O
PS/2 keyboard range as a standard resource marked as busy.  It prevents
the i8042 driver from registering as it fails to claim the resource in
a call to i8042_platform_init().  Consequently PS/2 keyboard and mouse
devices cannot be used with this platform.

Fix the issue by removing the busy marker from the standard reservation,
making the driver register successfully:

  serio: i8042 KBD port at 0x60,0x64 irq 1
  serio: i8042 AUX port at 0x60,0x64 irq 12

and the resource show up as expected among the legacy devices:

  00000000-00ffffff : MSC PCI I/O
    00000000-0000001f : dma1
    00000020-00000021 : pic1
    00000040-0000005f : timer
    00000060-0000006f : keyboard
      00000060-0000006f : i8042
    00000070-00000077 : rtc0
    00000080-0000008f : dma page reg
    000000a0-000000a1 : pic2
    000000c0-000000df : dma2
    [...]

If the i8042 driver has not been configured, then the standard resource
will remain there preventing any conflicting dynamic assignment of this
PCI port I/O address range.
