[PATCH] qe_lib: Remove immrbar_virt_to_phys() function

[Li Yang <leoli@freescale.com>]

Remove private physical address mapping routine in qe_lib.  Users
of qe_lib should use generic functions like iopa().
The change also addresses a bug found by Timur Tabi that cmd_input
got mapped in qe_issue_cmd().  It should be written to CECDR
unmodified.
