93b2f5799c crypto: qat - rename and relocate GEN2 config function 
Rename qat_crypto_dev_config() in adf_gen2_dev_config() and relocate it
to the newly created file adf_gen2_config.c.
This function is specific to QAT GEN2 devices and will be used also to
configure the compression service.

In addition change the drivers to use the dev_config() in the hardware
data structure (which for GEN2 devices now points to
adf_gen2_dev_config()), for consistency.

8f5c335e34 crypto: qat - simplify adf_enable_aer() 
A struct pci_driver is shared across all device instances, so assigning
pci_driver.err_handler once per device isn't really sensible.

Set adf_driver.err_handler statically instead of in adf_enable_aer().
This removes a use of pci_dev->driver, which is a step toward removing
pci_dev->driver altogether.

Since adf_enable_aer() returns zero unconditionally, make it a void
function.

3660f25186 crypto: qat - disable AER if an error occurs in probe functions 
If an error occurs after a 'adf_enable_aer()' call, it must be undone by a
corresponding 'adf_disable_aer()' call, as already done in the remove
function.

Add logic to detect device capabilities for c62x, c3xxx and dh895xcc.

by a device.

This patch is based on earlier work done by Conor McLoughlin.

Looking into the code:

  int ret, bar_mask;
    :
  for_each_set_bit(bar_nr, (const unsigned long *)&bar_mask,

It is casting a 32-bit integer pointer to a 64-bit unsigned long
pointer. There are two problems here. First, the 32-bit pointer address
may not be 64-bit aligned. Secondly, it is accessing an extra 4 bytes.

This is fixed by changing the bar_mask type to unsigned long.
