fix(fvp): increase EventLog size for OP-TEE with multiple SPs

When OP-TEE runs with multiple Secure Partitions (SPs), a larger
EventLog size is required to accommodate the additional measurements.
This patch updates the configuration to allocate sufficient memory
in such cases.

In the future, the Maximum EventLog size should be calculated based
on the maximum number of images loaded by BL2. That enhancement can
be addressed in a separate patch.
