Current qemu opensbi has different reserved sizes for 32bit and 64bit, caused by different MMU PMD sizes. But, when 64bit uses Sv32, the rule is changed. We can no longer use riscv_is_32bit to distinguish PMD sizes. Here we unify the 4MB reserved size for all PMD sizes, and the side effect is we lost 2MB of Linux system memory. This patch has been tested with opensbi fw_dynamic.bin, but the opensbi fw_jump.bin must be fixed after merging this patch.
