               riscv: Get rid of MAXPHYSMEM configs
               commit 
db1503d355a79d1d4255a9996f20e72848b74a56 upstream.
               CONFIG_MAXPHYSMEM_* are actually never used, even the nommu defconfigs
               selecting the MAXPHYSMEM_2GB had no effects on PAGE_OFFSET since it was
               preempted by !MMU case right before.
               In addition, the move of the kernel mapping at the end of the address
               space broke the use of MAXPHYSMEM_2G with MMU since it defines PAGE_OFFSET
               at the same address as the kernel mapping.
