[PATCH 3/3] drm/radeon/kms: use num_crtc instead of hard-coded value 6

[Ilija Hadzic]

radeon_driver_irq_preinstall_kms and radeon_driver_irq_uninstall_kms
hard code the loop to 6 which happens to be the current maximum
number of crtcs; if one day an ASIC with more crtcs comes out, this
is a trouble waiting to happen. it's better to use num_crtc instead
(for ASICs that have fewer than 6 CRTCs, this is still OK because
higher numbers won't be looked at)
