PCI: Move PCI_VENDOR_ID_VMWARE to pci_ids.h
Move PCI_VENDOR_ID_VMWARE from device-specific files to pci_ids.h.
It is useful to always have access to it, especially when accessing
subsystem_vendor_id on emulated devices.
[bhelgaas: keep pci_ids.h sorted and use lower-case hex]

[SCSI] vmw_pvscsi: Some improvements in pvscsi driver.
This change is about the following:
(1) If the number of targets is 16+ then default ring_pages to 32.
(2) Change default queue depth (per device) to 254.
(3) Implement change_queue_depth function so that queue_depth per device can
be changed at run time. Honors the request only if coming from sysfs.
(4) Clean up the info returned by modinfo.

[SCSI] vmw_pvscsi: Fix pvscsi_abort() function.
This change ensures that pvscsi_abort() function returns SUCCESS
only when the command in question was actually completed, otherwise
returns FAILURE. The code before change, was causing a bug where
driver tries to complete a command to the mid-layer while the mid-layer
has already requested the driver to abort that command, in response
to which the driver has responded with SUCCESS causing mid-layer
to free the command struct.

[SCSI] vmw_pvscsi: Try setting host->max_id as suggested by the device.
Fetch the config page from the device to learn max target id to set
host->max_id.
Also, fix some indentation issues and update the 'Maintained by' field.
