riscv: kexec: Align the kexeced kernel entry
The current riscv boot protocol requires 2MB alignment for RV64
and 4MB alignment for RV32.
In KEXEC_FILE path, the elf_find_pbase() function should align
the kexeced kernel entry according to the requirement, otherwise
the kexeced kernel would silently BUG at the setup_vm().
