fix(zynqmp): type cast addresses to fix overflow issue

Type cast the build time base and size argument to unsigned integer
and the limit derived from these two as unsigned long to avoid
size overflow issue during build.

For zynqmp platform, calculating the limit without typecasting results
in build error as follows

make -j DEBUG=0 RESET_TO_BL31=1 PLAT=zynqmp \
ZYNQMP_ATF_MEM_BASE=0x70000000 ZYNQMP_ATF_MEM_SIZE=0x10000000 \
XILINX_OF_BOARD_DTB_ADDR=0x100000 bl31

plat/xilinx/zynqmp/include/platform_def.h:51:62:
error: integer overflow in expression of type 'int' results
				in '-2147483648' [-Werror=overflow]
 51 | # define BL31_LIMIT   (ZYNQMP_ATF_MEM_BASE + ZYNQMP_ATF_MEM_SIZE)
