soc/intel/common: Helper function to check CSE device `devfn` status

This patch creates a helper function in cse common code block to check
the status of any CSE `devfn`. Example: CSE, CSE_2, IDER, KT, CSE_3 and
CSE_4.

Currently cse common code is only able to read the device state of
`PCH_DEVFN_CSE` CSE device alone.

Additionally, print `slot` and 'func' number of CSE devices in case
the device is either disable or hidden.

BUG=b:200644229
TEST=Able to build and boot ADLRVP-P with this patch where the serial
message listed the CSE devices that are disabled in the device tree
as below:

HECI: CSE device 16.01 is disabled
HECI: CSE device 16.04 is disabled
HECI: CSE device 16.05 is disabled
