CONFIG_MAXPHYSMEM_* were 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, I suspect that commit 2bfc6cd81bd1 ("riscv: Move kernel
mapping outside of linear mapping") which moved the kernel to
0xffffffff80000000 broke the MAXPHYSMEM_2GB config which defined
PAGE_OFFSET at the same address.
