Tegra: fixup GIC init from the 'on_finish' handler
Commit e9e19fb2fe684a740afc4820b3ee4cc38ad67d70 accidentally removed the GIC init routine required to initialze the distributor on system resume. This patch fixes this anomaly and initializes the distributor on system resume. Signed-off-by: Varun Wadekar <vwadekar@nvidia.com> Change-Id: I3fdc694404faa509952f2d90b1f16541165e583e
