This patch changes the type of the base address parameter in the ARM device driver APIs to uintptr_t (GIC, CCI, TZC400, PL011). The uintptr_t type allows coverage of the whole memory space and to perform arithmetic operations on the addresses. ARM platform code has also been updated to use uintptr_t as GIC base address in the configuration. Fixes ARM-software/tf-issues#214 Change-Id: I1b87daedadcc8b63e8f113477979675e07d788f1
