In this patch series we add a basic driver for Epson RX8111 RTC with
support for only reading/writing the time and the `ioctl`s `RTC_VL_READ`
and `RTC_VL_CLR`.
Datasheet: https://support.epson.biz/td/api/doc_check.php?dl=app_RX8111CE&lang=en
Changes in v3:
* Remove macro define `RX8111_DRV_NAME` for the driver name.
* Remove macro function `RX8111_TIME_BUF_IDX` and instead use the
offsets as indices directly.
* Remove `rx8111_setup()` that disabled extended functionality and
interrupts.
* Remove comments explaining register value conversions in
`rx8111_read/set_time()`.
* Check/clear register flag XST (oscillation stoppage) in
`rx8111_read/set_time()`.
* Change `vlval` to `unsigned int` in `rx8111_ioctl()`.
* Remove `case RTC_VL_CLR` in `rx8111_ioctl()`.
* Convert all `dev_err()` to `dev_dbg()`.
* Convert all `dev_err_probe()` to `dev_dbg()` in probe.
* Return without printing from `devm_rtc_register_device()` in probe.

Changes in v2:
