mlx5: Fix handling of port_module_event

Remove the array of port module status and instead save module status
and module number.

At boot, for each PCI function driver get event from fw about module
status. The event contains module number and module status. Driver
stores module number and module status.. When user (ifconfig) ask for
modules information, for each pci function driver first queries fw to
get module number of current pci function, then driver compares the
module number to the module number it stored before and if it matches
and module status is "plugged and enabled" then driver queries fw for
the eprom information of that module number and return it to the
caller.

In fact fw could have concluded that required module number of the
current pci function, but fw is not implemented this way. current
design of PRM/FW is that MCIA register handling is only aware of
modules, not the pci function->module connections. FW is designed to
take the module number written to MCIA and write/read the content
to/from the associated module's EPROM.

So, based on current FW design, we must supply the module num so fw
can find the corresponding I2C interface of the module to write/read.

ibcore: Kernel space update based on Linux 5.7-rc1.

Overview:

This is the first stage of a RDMA stack upgrade introducing kernel
changes only based on Linux 5.7-rc1.

This patch is based on about four main areas of work:
- Update of the IB uobjects system:
- The memory holding so-called AH, CQ, PD, SRQ and UCONTEXT objects
is now managed by ibcore. This also require some changes in the
kernel verbs API. The updated verbs changes are typically about
initialize and deinitialize objects, and remove allocation and
free of memory.

- Update of the uverbs IOCTL framework:
- The parsing and handling of user-space commands has been
completely refactored to integrate with the updated IB uobjects
system.

- Various changes and updates to the generic uverbs interfaces in
device drivers including the new uAPI surface.

- The mlx5_ib_devx.c in mlx5ib and related mlx5 core changes.

Dependencies:

- The mlx4ib driver code has been updated with the minimum changes
needed.

- The mlx5ib driver code has been updated with the minimum changes
needed including DV support.

Compatibility:

- All user-space facing APIs are backwards compatible after this
change.

- All kernel-space facing RDMA APIs are backwards compatible after
this change, with exception of ib_create_ah() and ib_destroy_ah()
which takes a new flag.

- The "ib_device_ops" structure exist, but only contains the driver ID
and some structure sizes.

Differences from Linux:

- Infiniband drivers must use the INIT_IB_DEVICE_OPS() macro to set
the sizes needed for allocating various IB objects, when adding
IB device instances.

Security:

- PRIV_NET_RAW is needed to use raw ethernet transmit features.
- PRIV_DRIVER is needed to use other privileged operations.

Based on upstream Linux, Torvalds (5.7-rc1):

Update user access region, UAR, APIs in the core in mlx5core.

This change include several changes as listed below all related to UAR.
UAR is a special PCI memory area where the so-called doorbell register and
blue flame register live. Blue flame is a feature for sending small packets
more efficiently via a PCI memory page, instead of using PCI DMA.

- All structures and functions named xxx_uuars were renamed into xxx_bfreg.
- Remove partially implemented Blueflame support from mlx5en(4) and mlx5ib.
- Implement blue flame register allocator.
- Use blue flame register allocator in mlx5ib.
- A common UAR page is now allocated by the core to support doorbell register
writes for all of mlx5en and mlx5ib, instead of allocating one UAR per
sendqueue.
- Add support for DEVX query UAR.
- Add support for 4K UAR for libmlx5.
