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.
