30ecf67308 net/qede/base: remove unused parameters
This is an attempt to clean up many unused API parameters across the base
code. Most of the changes are related to removing unused p_hwfn or p_ptt
handlers. The warnings are generated using 'unused-parameter' cflags.

e916697f8e net/qede/base: support doorbell overflow recovery
Add support for doorbell overflow recovery mechanism:
The doorbell recovery mechanism consists of a list of entries which
represent doorbelling entities (l2 queues, roce sq/rq/cqs, the slowpath
spq, etc). Each entity needs to register with the mechanism and provide
the parameters describing it's doorbell, including a location where last
used doorbell data can be found. The doorbell execute function will
traverse the list and doorbell all of the registered entries.

22c996968b net/qede/base: revise management FW mbox access scheme
Revise the manamgement FW mbox access locking scheme for the access to the
MFW mailbox:
 - add a new linked list called cmd_list to ecore_mcp_info that tracks all
   the mailbox commands sent to management FW and ones waiting for
   response.
 - add a mutex lock called cmd_lock to ecore_mcp_info, a spinlock used to
   serialize the access to this cmd_list and makes sure that the mbox is
   not a pending one before sending a new mbox request. It protects the
   access to the mailbox commands list and sending of the commands.
 - add ecore_mcp_cmd_add|del|get_elem() APIs for new access scheme
 - remove ecore_mcp_mb_lock() and ecore_mcp_mb_unlock()
 - add a mutex lock called link_lock to ecore_mcp_info, a spinlock used for
   syncing SW link-changes and link-changes originating from attention
   context. This locking scheme prevents possible race conditions that may
   occur, such as during link status reporting.
 - Surround OSAL_{MUTEX,SPIN_LOCK}_{ALLOC,DEALLOC} with
   '#ifdef CONFIG_ECORE_LOCK_ALLOC'. In case memory has to be allocated for
   lock primitives, then compile driver with CONFIG_ECORE_LOCK_ALLOC flag.

739a5b2f2b net/qede/base: use passed ptt handler
Use the ptt[PF translation table] handler that is passed rather than using
main ptt from the HW function.
In ecore_hw_get_resc()'s error flow, release the MFW generic resource lock
only if needed.
Change the verbosity level of GRC timeout from DP_INFO() to DP_NOTICE().
Reduce verbosity of print in ecore_hw_bar_size().

869c47d051 net/qede/base: add support for new firmware
Add support for 8.14.x.x firmware.

The new firmware adds support for external PHY BCM8485x; configures
fixed link speed with transceiver/cable not supporting negotiation;
supports engine swap; supports overriding PCIe preset equalization
value; checks pause too long for ports and reads die temperature
every second for shutdown threshold.
It includes change in FLR flow when there is a SW initiated FLR.

ec94dbc573 qede: add base driver
The base driver is the backend module for the QLogic FastLinQ QL4xxxx
25G/40G CNA family of adapters as well as their virtual functions (VF)
in SR-IOV context.

The purpose of the base module is to:
 - provide all the common code that will be shared between the various
   drivers that would be used with said line of products. Flows such as
   chip initialization and de-initialization fall under this category.
 - abstract the protocol-specific HW & FW components, allowing the
   protocol drivers to have clean APIs, which are detached in its
   slowpath configuration from the actual Hardware Software Interface(HSI).

This patch adds a base module without any protocol-specific bits.
I.e., this adds a basic implementation that almost entirely falls under
the first category.
