[Lucid] [PATCH v2] SRU: UBUNTU: SAUCE: Fix hang on resume for Dell Studio 1558, 1557, 1555

[Kamal Mostafa]

Proposed patch for Lucid SRU-

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/553498
Dell Studio 1558 (Arrandale) hangs on resume from suspend

SRU Justification/Impact:

Dell Studio 1558 (and presumably other 155x models) hangs on resume from
suspend.

TEST CASE:

I have built and tested a kernel with this patch and confirmed that it
reliably fixes resume from suspend on my own Dell Studio 1558.

=====

Add the Dell Studio models (1558, 1557, 1555) to the list of machines
needing 'set_sci_en_on_resume' handling; affects only the listed models.
