[dpdk-dev] [PATCH v3 4/5] raw/ifpga/base: free resources when destroying ifpga device

[Tianfei zhang <tianfei.zhang@intel.com>]

From: Wei Huang <wei.huang@intel.com>

Add two functions to complete the resource free work, one is
'ifpga_adapter_destroy()', the other is 'ifpga_bus_uinit()'.

Then call 'opae_adapter_destroy()' and 'opae_adapter_data_free()'
in 'ifpga_rawdev_close()' to free resources.

Also 'opae_adapter_free()' is removed from 'ifpga_rawdev_destroy()',
because opae adapter is pointed by dev_private member in raw_dev,
it will be freed in 'rte_rawdev_pmd_release()'.

v3: Free the driver resouce on rawdev close ops.
