drivers/i2c/rv3028c7: Add ACPI generation callbacks

Add ACPI generation callback to the driver after obtaining the
ACPI HID "MCRY3028" for this device from Microcrystal AG (VID: "MCRY").

Also add I2C bus speed field to the device config structure, which
is a required ACPI entry.

BUG=none
TEST=Disassemble the SSDT table and see whether the device entry
"MC28" is generated correctly. Also check whether the RV3028 driver
in Linux (drivers/rtc/rtc-rv-3028.c) is bound correctly after adding
an ACPI match table to it containing the HID. A proper kernel patch
is pending.
