disp: msm: expose qsync avr step as part of conn mode caps

Add capability to read avr step for each timing mode. This will be in addition to the existing avr-step-list which is defined when dfps is enabled. Expose the avr-step as part of each mode in connector caps to user-mode. Additionally, change the avr_step connector property to enum to give usermode just the capability to enable/disable avr-step and not alter the step value as its fixed from the device tree.
