ACPI: request correct fixed hardware resource type (MMIO vs I/O port)

ACPI supports fixed hardware (PM_TMR, GPE blocks, etc) in either I/O port
or MMIO space, but used to always request the regions from I/O space
because it didn't check the address_space_id.

Sample ACPI fixed hardware in MMIO space (HP rx2600), was incorrectly
reported in /proc/ioports, now reported in /proc/iomem:

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