Currently, each I/O EQ is taking 128KB of memory. This size
is not needed in all use cases, and is critical with large scale.
Hence, allow user to configure the size of I/O EQs.

For example, to reduce I/O EQ size to 64, execute:
$ devlink resource set pci/0000:00:0b.0 path /io_eq_size/ size 64
$ devlink dev reload pci/0000:00:0b.0
This sort of config is needed by more drivers,
we need a standard way of configuring this.

Sorry, I didn't have the time to look thru your patches
yesterday, I'm sending a revert for all your new devlink
params.
