accel/ivpu: Do not initialize parameters on power up

Browse Source 
[ Upstream commit f956bf2080862cfc97412e1eaa08689bc9838d20 ]

Initialize HW specific parameters only once. We do not have to do this
on every power_up (performed during initialization and on resume). Move
corresponding code to ->info_init()
