PNPACPI: add support for HP vendor-specific CCSR descriptors

The HP CCSR descriptor describes MMIO address space that should appear
as a MEM resource.  This patch adds support for parsing these descriptors
in the _CRS data.

The visible effect of this is that these MEM resources will appear
in /sys/devices/pnp0/.../resources, which means that "lspnp -v" will
report it, user applications can use this to locate device CSR space,
and kernel drivers can use the normal PNP resource accessors to
locate them.
