[PATCH net-next 4/8] mlxsw: core: Move resource query API to common location

[Ido Schimmel]

From: Vadim Pasternak <vad...@mellanox.com>

Move mlxsw_pci_resources_query() to a common location to allow reuse by
the different drivers and over all the supported physical buses. Rename
it to mlxsw_core_resources_query().
