[PATCH 0/2 v7] Lattice MachXO2 Slave SPI FPGA Manager support

[Paolo Pisati]

Hi all,
this series adds support for the Lattice MachXO2 FPGA chip, programmed
over Slave SPI.

Tested on a raspberry pi3, beaglebone black (little endian mode) and imx6
hummingboard (big endian mode) + bugblat's pif2 fpga hat (machxo2 7000HC) or
tinyfpga A1/A2 (machxo2 256HC / 1200HC), in SPI slave mode with varying bus
speed.

Changes since v6:
* added the SPDX boilerplate
* switched to pr_debug() and renamed MACHXO2_DEBUG to DEBUG
