src/drivers/i2c/rx6110sa: Omit _HID temporarily

The current HID "RX6110SA" does not comply with the ACPI spec in terms
of the naming convention where the first three caracters should be a
vendor ID and the last 4 characters should be a device ID. For now
there is a vendor ID for Epson (SEC) but there is none for this
particular RTC. In order to avoid the reporting of a non ACPI-compliant
HID it will be dropped completely for now.

Once Epson has assigned a valid HID for this RTC, this valid HID will be
used here instead.
