{commonlib, lib}: Add timestamp for early chip initialization

This commit introduces a new timestamp `TS_DEVICE_INIT_CHIPS` to
specifically mark the start of the `dev_initialize_chips()` function.

Previously, the `TS_DEVICE_ENUMERATE` timestamp was incorrectly
associated with the `bs_dev_init_chips` function.

This patch corrects this by:

- Adding the `TS_DEVICE_INIT_CHIPS` enum and name definition.
- Updating `bs_dev_init_chips` in `src/lib/hardwaremain.c` to use
  `TS_DEVICE_INIT_CHIPS`.
- Moving the `TS_DEVICE_ENUMERATE` timestamp addition to the
  `bs_dev_enumerate` function where device enumeration actually begins.

This change provides a more accurate and meaningful timestamp for the
early chipset initialization phase.

TEST=Able to build and boot google/fatcat.
