tegra_bootloader_debug: Register resume callbacks

1. Register resume_noirq handler for profiling the time when early
driver resume sequence is started. Since this driver is loaded after
boot, this should get called very early in the resume sequence.

2. Register PM notifier to know when resume is complete. This helps
in profiling the time when entire resume sequence is complete.

These 2 timestamps should approximately indicate the time it takes
for Linux to resume.

Adding this code in this driver removes dependency of providing this
information from some other driver.
