feat(fvp): add Event Log maximum size property in DT
Updated the code to get and set the 'tpm_event_log_max_size' property
in the event_log.dtsi.
In this change, the maximum Event Log buffer size allocated by BL1 is
passed to BL2, rather than both relying on the maximum Event Log buffer
size macro.
