[patch 1/7] input: bcm5974: retract efi-broken suspend_resume

[akpm]

From: "Henrik Rydberg" <rydberg@euromail.se>

With the recent system-wide improvements on suspend/resume and EFI booting
the suspend_resume method of the bcm5974 has broken.  When waking up from
the S3 state on the MacBookAir, the trackpad is found in a yet unknown
state, unable to switch to the proper multitouch mode.  The result is a
frozen touchpad, and a flood of errors of the kind

bcm5974: bad trackpad package, length: 8.

This patch retracts the reset_resume method altogether, falling back on
the generic unbind/rebind functionality of the usb layer until further
investigations can be made as how to reset the device when booting from
efi.
