ACPI: Display "ACPI" to motherboard resources in /proc/io{mem,port}

ACPI: Display "ACPI" to motherboard resources in /proc/io{mem,port}

Add "ACPI" to motherboard resource allocation names, so people have a clue
about where to look.  And remove some trailing spaces.

Changes these /proc/iomem entries from this:

    ff5c1004-ff5c1007 : PM_TMR
    ff5c1008-ff5c100b : PM1a_EVT_BLK
    ff5c100c-ff5c100d : PM1a_CNT_BLK
    ff5c1010-ff5c1013 : GPE0_BLK
    ff5c1014-ff5c1017 : GPE1_BLK

to this:

    ff5c1004-ff5c1007 : ACPI PM_TMR
    ff5c1008-ff5c100b : ACPI PM1a_EVT_BLK
    ff5c100c-ff5c100d : ACPI PM1a_CNT_BLK
    ff5c1010-ff5c1013 : ACPI GPE0_BLK
    ff5c1014-ff5c1017 : ACPI GPE1_BLK
