Added nbnxn_ocl_pme_loadbal_update_param for OpenCL

1. Added implementation and call for nbnxn_ocl_pme_loadbal_update_param
2. Removed HAS_CC_3_0_OR_LATER
3. Updated init_ewald_coulomb_force_table function
4. Updated pick_ewald_kernel_type function
Temporary disabled kernel fastgen

eeltype can change during one working session, so the current
implementation for kernel fastgen does not work correctly.
