pcdp: use early_ioremap/early_iounmap to access pcdp table

efi_setup_pcdp_console() is called during boot to parse the HCDP/PCDP EFI
system table and setup an early console for printk output.  The routine
uses ioremap/iounmap to setup access to the HCDP/PCDP table information.
The call to ioremap is happening early in the boot process which leads to
a panic on x86_64 systems:

    0xffffffff81d19341 x86_64_start_reservations+0x012c
    0xffffffff81d19449 x86_64_start_kernel+0x00fe

This patch replaces the calls to ioremap/iounmap in
efi_setup_pcdp_console() with calls to early_ioremap/early_iounmap which
can be called during early boot.

This patch was tested on an x86_64 prototype system which uses the
HCDP/PCDP table for early console setup.

mm: fix wrong argument of migrate_huge_pages() in soft_offline_huge_page()

a6bc32b899223 ("mm: compaction: introduce sync-light migration for use by
compaction") changed the declaration of migrate_pages() and
migrate_huge_pages().  But it missed changing the argument of
migrate_huge_pages() in soft_offline_huge_page().  In this case, we should
call migrate_huge_pages() with MIGRATE_SYNC.

Additionally, there is a mismatch between type the of argument and the
function declaration for migrate_pages().
