ARM: mm: fix boot on SA1110 Assabet

commit 319e0b4f02f73983c03a2ca38595fc6367929edf upstream.

Commit 83db0384 (mm/ARM: use common help functions to free reserved
pages) broke booting on the Assabet by trying to convert a PFN to
a virtual address using the __va() macro.  This macro takes the
physical address, not a PFN.  Fix this.
