Mellanox: Add new mlxsw_spectrum firmware xx.2010.1502

Add latest verified version of Nvidia Spectrum-family switch firmware,
for Spectrum (13.2010.1502), Spectrum-2 (29.2010.1502) and Spectrum-3
(30.2010.1502). Furthermore, add lc_ini_bundle_2010_1502.bin.xz for
modular systems.

The following issues have been fixed:

- CRC errors when using 25Gbps links in a modular system.
- Issue in bring-up of line-card no. 8 in a modular system.
- Several issues with too-long link-up times.
- An interop issue with Broadcom Tomahawk.
- An issue that might cause dropping first several packets after a port
  speed is changed to 400Gbps 8x.
- A switch freeze which might occur after many 10Gbps ports get disabled
  simultaneously.
- Latency degradation of RALUE EMAD processing.
- An issue in port isolation, which would not work on two-way split port 64
  on Spectrum-1, and four-way split port 128 on Spectrum-2 and Spectrum-3.
- Issue in multicast configuration on port 128 on Spectrum-2 and
  Spectrum-3.
- On Spectrum-2 systems, when receiving a packet with Symbol Errors on
  ports that are configured to cut-thought, in some cases, a pipeline may
  get stuck.
- Several issues in autonegotiation.

In addition, the following improvement has been made:

- Support in FW for reporting module values to the SW.
