arm: mach-k3: introduce new config option for sysfw split 

On J7 family of SoCs (J721E and J7200), sysfw is being split to be run
under two cores, TIFS portion on DMSC core, and DM firmware under MCU
R5. As MCU R5 is also used to run one phase of the bootloader, we must
prevent access from here towards sysfw services. To support this, add
new config option which can be used to detect presence of RM/PM sysfw
services.

Enabling this will indicate that the system has separate DM
and TIFS firmware images in place, instead of a single SYSFW
firmware. Due to DM being executed on the same core as R5 SPL
bootloader, it makes RM and PM services not being available
during R5 SPL execution time.
