All Qualcomm bootloaders log useful timestamp information related

This basically copies the name of node, so not really helpful. Describe
what's this.

No underscores in compatibles. Why this is not SoC specific compatible?

Ack. The boot_stats module is not specific to a device. It is written to
read some values from this imem region which is present for almost all QCOM SoCs. So SoC specific compatible is not given in this case.

Drop description, it's obvious.
