Subject: [PATCH v3 0/2] [RESEND] Lattice MachXO2 Slave SPI FPGA Manager support

Hi all,

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

Tested on my raspberry pi3 + bugblat's pif2 fpga hat.

Changes from v1:
* fixed all the warnings pointed out by 'checkpatch --strict' and
  Alan Tull

Changes from v2:
* convert to BIT() macro and spi_message_init() / trans.delay_usecs
