[v2,00/32] add support for baseband phy

  This series adds initial support for baseband PHY available on SOCs
belonging to Fusion family. BPHY is a hardware block comprising
accelerators and DSPs specifically tailored for 5G/LTE inline usecases.

This series introduces two rawdev PMDs along with low level common code.

CGX/RPM PMD allows one to configure Ethernet I/O interfaces attached to
BPHY via standard enqueue/dequeue operations.

BPHY PMD provides an out-of-band access to PCI device BARs and a set of
experimental APIs allowing one to setup custom IRQs handlers. This
functionality is backed by kernel module using ioctl() mechanism. Series
has nothing to do with 5G/LTE baseband protocol processing.

v2:
- change some errors to more relevant ones (-EINVAL/-ENODEV)
- fix MAINTAINERS styling issues
- fix dpdk-devbind.py
- fix meson.build styling issues
- fix warning related to possibly uninitialized scr0 variable
- fix warning releated to unused function
- improve documentation
- improve enums items naming
- spread documentation across relevant patches

This series looks good to me.
Feel free to add my reviewed by for the series after fix the following

1) Typo
diff --git a/doc/guides/rawdevs/cnxk_bphy.rst b/doc/guides/rawdevs/cnxk_bphy.rst
-``CNXK_BPHY_CGX_MSG_TYPE_INTLBK_DISABLE``. Former will activate
internal loobback while the latter
+``CNXK_BPHY_CGX_MSG_TYPE_INTLBK_DISABLE``. Former will activate
internal loopback while the latter

2) checkpatch
WARNING:LONG_LINE: line length of 85 exceeds 80 columns
#88: FILE: drivers/common/cnxk/roc_bphy_cgx.c:77:
+               if (FIELD_GET(SCR0_ETH_EVT_STS_S_EVT_TYPE, *scr0) ==
ETH_EVT_ASYNC &&

3) In the release notes, the following items can be removed.

+  Added new Baseband phy PMD which provides means for configuring
baseband hardware via
+  standard rawdev enq/deq operations. Baseband phy is a hardware
subsystem accelerating
+  5G/LTE related tasks.
+
+  Both BPHY and BPHY CGX/RPM drivers are related hence kept together
to ease maintenance.
