RISC-V: mm: Fix set_satp_mode() for platform not having Sv57
When Sv57 is not available the satp.MODE test in set_satp_mode() will
fail and lead to pgdir re-programming for Sv48. The pgdir re-programming
will fail as well due to pre-existing pgdir entry used for Sv57 and as
a result kernel fails to boot on RISC-V platform not having Sv57.
To fix above issue, we should clear the pgdir memory in set_satp_mode()
before re-programming.
