ec/google/chromeec: Fix dev ops for chromeec

CB:38541 ("ec/google/chromeec: Add SSDT generator for ChromeOS EC")
added a new device_operations structure for chromeec for handling ACPI
SSDT generation. However, this resulted in the original
device_operations which handled lpc read resources to be skipped. This
change fixes the above regression by combining the device operations
for reading resources and ACPI SSDT generation into a single structure
and retains the old logic for enabling of pnp devices.
