[PATCH v6 3/5] baseband/acc100: introduce PMD for ACC101

[Nicolas Chautru <nicolas.chautru@intel.com>]

Support for ACC101 as a derivative of ACC100.
Integrated in unified driver and reusing existing code when possible.

-==========================================
+Intel(R) ACC100 and ACC101 5G/4G FEC Poll Mode Drivers

 The BBDEV ACC100 5G/4G FEC poll mode driver (PMD) supports an
 implementation of a VRAN FEC wireless acceleration function.
 This device is also known as Mount Bryce.
+The BBDEV ACC101, also known as Mount Cirrus, is a derivative device from Mount Bryce
