The VACG interrupt was not being enabled.  Thus, interrupts were never
generated when AC status changes.  In addition, interrupts were never
cleared after taking and processing the interrupt.

Added the register offset for the INTR_MASK register, since this is needed
to unmask the VACG interrupt.

Enabled the VACG interrupt in tps65090_config_charger().

Cleared interrupts after processing, in tps65090_charger_isr().

Also removed unused variable "enable" in tps65090_enable_charging(), and
fixed a typo in one of the dev_err() prints.

If enabled, CONFIG_PARPORT_PC_SUPERIO scans on PC-like hardware for
various super-io chips by accessing i/o ports in a range which will
crash any parisc hardware at once.

In addition, parisc has it's own incompatible superio chip
(CONFIG_SUPERIO), so if we disable PARPORT_PC_SUPERIO completely for
parisc we can avoid that people by accident enable the parport_pc
superio option too.

   parisc/PCI: lba: convert to pci_create_root_bus() for correct root bus
                    resources

  Supply root bus resources to pci_create_root_bus() so they're correct
  immediately.  This fixes the problem of "early" and "header" quirks seeing
  incorrect root bus resources.

added tests for elmmio_space.start while it should use
elmmio_space.flags.  This for example led to incorrect resource
assignments and a non-working stifb framebuffer on most parisc machines.

LBA 10:1: PCI host bridge to bus 0000:01
pci_bus 0000:01: root bus resource [io  0x12000-0x13fff] (bus address [0x2000-0x3fff])
pci_bus 0000:01: root bus resource [mem 0xfffffffffa000000-0xfffffffffbffffff] (bus address [0xfa000000-0xfbffffff])
pci_bus 0000:01: root bus resource [mem 0xfffffffff4800000-0xfffffffff4ffffff] (bus address [0xf4800000-0xf4ffffff])

The non-PAT resource probing code failed to set the type of the LBA bus_num

'path.bc[i]' can be asigned by PCI_SLOT() which can '> 10', so sizeof(6
* "%u:" + "%u" + '\0') may be 21.

Since 'name' length is 20, it may be memory overflow.

And 'path.bc[i]' is 'unsigned char' for printing, we can be sure the
max length of 'name' must be less than 28.

So simplify thinking, we can use 28 instead of 20 directly, and do not
think of whether 'patchc.bc[i]' can '> 100'.

  Linux doesn't use them but they are simple and I'm not comfortable
  having a half-implemented interface in 3.10 and having to deal with
  versionning etc...  later when something starts needing those calls.
  They cannot be emulated in qemu when using in-kernel interrupt
  controller (not enough shared state).
