V4L/DVB: ir: Make sure that the spinlocks are properly initialized

Some spinlocks are not properly initialized on ir core:

[  471.714132] BUG: spinlock bad magic on CPU#0, modprobe/1899
[  471.719838]  lock: f92a08ac, .magic: 00000000, .owner: <none>/-1, .owner_cpu: 0
[  471.727301] Pid: 1899, comm: modprobe Not tainted 2.6.33 #36
[  471.733062] Call Trace:

[  471.744224]  [<c126962d>] do_raw_spin_lock+0x7d/0x160
[  471.749364]  [<f92a01ff>] ? ir_rc5_register+0x6f/0xf0 [ir_rc5_decoder]

So, use static initialization for the static spinlocks, instead of the
dynamic ones (currently used), as proposed by David Härdeman on one
of his RFC patches.
