Song Shuai 1bfb2b618d 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().

Fixes: 8acea455fa ("RISC-V: Support for kexec_file on panic")
