The RockPro64 board has a PCIe slot that can be used with a slim
NVMe M.2 SSD drive. This makes attaching an external drive unnecessary
and can allow for a nice compact form factor.
The partition naming scheme is a bit different. While on regular USB
drives partitions are called e.g. /dev/sda1, on an NVMe drive the
partition is called /dev/nvme0n1p1 (note the appendix 'p1' instead
of '1')
This commit extends the script 'mount_drive.tcl' to
* recognize blockdevices starting with 'nvme' in findBlockDevices()
* use the variable $blockPartition in createMyNodeFsOnBlockDevice() to
allow for the different partition naming scheme
