arm-bsp/secure-partitions: corstone1000: Increase SMM Gateway variable handling capacity

Browse Source 
The maximum number of UEFI variables that can be supported by SMM
gateway is currently 40. When more than 40 variables are written,
or read SMM gateway returns error code. Currently this value is
increased to 100 to support more UEFI variables.
