Subject: [PATCH 2/8] drm/arm/malidp: Modified the prototype of malidp_se_irq_fini

'struct drm_device' is being replaced with 'struct malidp_hw_device'
as the function argument.The reason being the dependency of
malidp_se_irq_fini on 'struct drm_device' needs to be removed so as to
enable it to call from functions which receives 'struct malidp_hw_device'
as argument. Furthermore, there is no way to retrieve 'struct drm_device'
from 'struct malidp_hw_device'
