i3c: Fix default I2C adapter timeout value

Commit 3a379bbcea0a ("i3c: Add core I3C infrastructure") set the default adapter timeout for I2C transfers as 1000 (ms). However that parameter is defined in jiffies not in milliseconds.

With mipi-i3c-hci driver this wasn't visible until commit c0a90eb55a69 ("i3c: mipi-i3c-hci: use adapter timeout value for I2C transfers").

Fix this by setting the default timeout as HZ (CONFIG_HZ) not 1000.

---
v2:
- Stable Cc'ed just in case. While the incorrect default timeout value was introduced back in v5.0 it became visible only due to commits in v6.17-rc1 and if CONFIG_HZ != 1000.
- Added Fixes tag for the Renesas I3C controller. Thanks to Wolfram Sang <[email protected]> for noticing.
- Added Reviewed-by tags from Frank and Wolfram.
