From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

Update the `riic_init_hw()` function to use the local `dev` pointer in
calls to `dev_err_probe()`. Previously, `riic_init_hw()` used
`riic->adapter.dev` in error reporting. Since this function is invoked
during the probe phase, the I2C adapter is not yet initialized, leading to
`(null) ...` being printed in error messages. This patch fixes the issue
by consistently using the local `dev` pointer, which points to
`riic->adapter.dev.parent`.
