RISC-V: Define MAXPHYSMEM_1GB only for RV32
MAXPHYSMEM_1GB option was added for RV32 because RV32 only supports 1GB of maximum physical memory. This lead to few compilation errors reported by kernel test robot which created the following configuration combination which are not useful but can be configured. 1. MAXPHYSMEM_1GB & RV64 2, MAXPHYSMEM_2GB & RV32 Fix this by restricting MAXPHYSMEM_1GB for RV32 and MAXPHYSMEM_2GB only for RV64.
