PCI/ACPI: Rename _HPX structs from hpp_* to hpx_*
The names of the hpp_type0, hpp_type1 and hpp_type2 structs suggest that they're related to _HPP, when in fact they're related to _HPX. The struct hpp_type0 denotes an _HPX Type 0 setting record that supersedes the _HPP setting record, and it has been used interchangeably for _HPP as per the ACPI specification (see version 6.3, section 6.2.9.1) which states that it should be applied to PCI, PCI-X and PCI Express devices, with settings being ignored if they are not applicable. Rename them to hpx_type0, hpx_type1 and hpx_type2 to reflect their relation to _HPX rather than _HPP.
