fix(rpi3): expose BL1_RW to BL2 map for mboot

Browse source 
BL2 requires the ability to access the TCG Event Log during
Measured Boot. Currently the Platform hangs since the Event Log
is not exposed to BL2's mmap. Define a RPI3_BL1_RW region to be
added to the BL2 Image, if Measured Boot is enabled.
