soc/intel/ptl: Change ACPI name for IPU
Change IPU name to 4 characters: IPU0
While the ACPI device name is 'IPU', some part of generated SSDT looks
for 'IPU_', since by convention, the names less than 4 characters is
padded with underscope ("_"). Please see APCI spec 5.3 ACPI Namespace.
BUG=none
TEST=Boot fatcat board to OS and check that IPU device name is IPU0 in
the SSDT.
