ARM: socfpga: Convert callers of cm_write_with_phase for wait_for_bit_le32

Now that we have and use wait_for_bit_le32() available, the callers of
cm_write_with_phase() should not be casting values to u32 and instead we
expect a const void *, so provide that directly.

Fixes: 48263504 ("wait_bit: use wait_for_bit_le32 and remove wait_for_bit")
