Move dynamic sections and relocation sections data structures to

parameter struct Elf64_Dyn *dynamic is not used by x86-64 now because

this patch calculate riscv static pages number for page pool.
riscv donot need to map guest memory. use link script address
label to map code size.
For risc-v:
1) if the platform doesn't support PCIe devices
The address space layout for risc-v is like
| |
| MMIO |
| |
| ... |
| |
| RAM |
| |
For all its address space, one 1GB page table is enough which cover 512G
For MMIO or RAM, if its start address and end address is 1G aligned, there's no 2M
or 4K page table is needed. if their address are not 1G aligned, two 2M page table
is enough for MMIO or RAM. The issue here is that if we neetid 4K page entries for
different page attributes. So we need to reserve enough 4K page tables for that requirement.
2) if the platform support PCI devices, for the low MMIO range, another two 2MB page
table may needed. for the high MMIO range, its depends on the max physical address bits of
the platform and the high MMIO range reserved by the BIOS.

The RISC-V calling convention defines a full descending stack, where 'sp'
points to the last used stack address. The current implementation of
cpu_ctx_save() subtracts only CPU_REGS_OFFSET_SCRATCH from 'sp', which
allocates 8 bytes too few and may overwrite the caller's stack contents.
Fix this by adjusting CPU_REGS_OFFSET_LAST to include the last slot,
ensuring the full context save/restore area is properly reserved.
Fixes: 6276763cd (hv: riscv: implement cpu_ctx_save and cpu_ctx_restore)
