soc/intel/*: Correct ACPI device name for eMMC

The ACPI name of any device needs to match the name used for generating
the S0i3 LPI constraint list, which comes from soc_acpi_name() for each
SoC. The names used for the eMMC controller do not match, which will
lead to broken ACPI tables since the LPI constriant will reference
an ACPI device which does not exist. Some OSes tolerate this better
than others, but it should still be corrected.

TEST=build/boot google/{hatch,volteer, brya}, dump ACPI and verify
no invalid device names referenced.
