src/drivers/i2c/rx6110sa: Add official ACPI ID

In patch CB:47706 the randomly and therefore wrong assigned ACPI ID for
RTC RX6110SA was removed. In the meantime Seiko-Epson did a great job
and have registered an official vendor ID in the ACPI database [1].
Further on, Seiko-Epson have now assigned the unique Product Identifier
for the RX6110SA, which is '6110'. The assignment of the Product
Identifier is controlled by the vendor and there is no official database
where this ID is stored in. It is up to the vendor to make sure that
this ID stays unique.

This patch adds this new vendor and product ID to the driver. Together
with a pending Linux patch this RTC is now useable as ACPI device in
Linux.
