Older version wasn't providing full support for PMR setup, this one
does.
Rewrite get-pmr such that it supports CMB/PMR sizes greater than 4GB.
Also, since CMB and PMR can coexist in newer versions of qemu try to
detect both under single device.
E.g.:
nvme0:0000:00:04.0:64-bit:prefetchable:0x700000000:0x707ffffff:0x08000000:cmb
nvme0:0000:00:04.0:64-bit:prefetchable:0x400000000:0x5ffffffff:0x200000000:pmr
nvme1:0000:00:05.0:64-bit:prefetchable:0x708000000:0x70fffffff:0x08000000:cmb

Added mainly to verify if the PMR setup on the VM is correct.
Example of an output with PMR device size of 32M configured for
two nvme devices, and one nvme device with 128M CMB.
