ENGR00240988: gpu: fix deprecated idr calls on 3.10 kernel

The idr calls idr_pre_get() and idr_get_new_above() are deprecated on
3.10 kernel and cause the following build issues.  Replace the calls
with the new idr_alloc() to fix the issue.

drivers/mxc/gpu-viv/hal/os/linux/kernel/gc_hal_kernel_os.c: In function ‘_AllocateIntegerId’:
