ipa: ipu3: Consolidate querying of exposure and gain limits
The exposure and gain limits are required for AGC configuration handled in IPAIPU3::updateSessionConfiguration(), which is happening already. Therefore the max/min private members in IPAIPU3 class for exposure/gain serve no use except setting initial values of exposure_ and gain_ members. Drop the max/min private members from IPAIPU3 class and set initial gain_ and exposure_ in IPAIPU3::updateSessionConfiguration().
