ACPI: suspend: restore BM_RLD on resume

In 2.6.29,
31878dd86b7df9a147f5e6cc6e07092b4308782b
"ACPI: remove BM_RLD access from idle entry path"
moved BM_RLD initialization to init-time from run time.

But we discovered that some BIOS do not restore BM_RLD
after suspend, causing device errors on C3 and C4
after resume.  So now the kernel restores BM_RLD.
