The rings structure in bank is allocated dynamically based on the number of banks supported by a device. Note that in the error path in adf_init_bank(), ring->inflights is set to NULL after the free to silence a false positive double free reported by clang scan-build.

This patch separates the logic that configures the iov threads in a common function that takes as input the number of AE2FUNC_MAP registers supported by a device. The function is then added to the adf_hw_device_data structure of each device, and called with the appropriate parameters. The configure iov thread logic is added to a new file, adf_gen2_hw_data.c, that is going to contain code that is shared across QAT GEN2 devices.

This patch reworks the gen-specific parts of the arbiter access code by introducing the arb_info structure, that contains the values that are generation specific, and a function in the structure adf_hw_device_data, get_arb_info(), that allows to get them. Since the arbiter values for QAT GEN2 devices (c62x, c3xxx and dh895xcc) are the same, a single function, adf_gen2_get_arb_info() is provided in adf_gen2_hw_data.c and referenced by each QAT GEN2 driver.
