This patch adds support for RMM granules allocation in FVP 2nd DRAM 2GB bank at 0x880000000 base address. For ENABLE_RME = 1 case it also removes "mem=1G" Linux kernel command line option in fvp-base-psci-common.dsti to allow memory layout discovery from the FVP device tree. FVP parameter 'bp.dram_size' - size of main memory in gigabytes documented in docs/components/realm-management-extension.rst is changed from 2 to 4.
