A couple of reliability improvements for Microchip Polarfire FPGA
manager:
 * move SPI I/O buffers out of stack
 * rewrite status polling routine in a time measurable way

Also improve mpf_ops_write() code readability by separating single data
frame writing routine.

ChangeLog:
  v1:
[https://lore.kernel.org/linux-fpga/20221223123854.8023-1-i.bornyakov@metrotek.ru/]
  v2:
    * split into 3 distinct patches
[https://lore.kernel.org/linux-fpga/20221226142326.8111-1-i.bornyakov@metrotek.ru/]
  v3:
    * fix polling stop condition in mpf_poll_status() as Ilpo suggested.
[https://lore.kernel.org/linux-fpga/20221227100450.2257-1-i.bornyakov@metrotek.ru/]
  v4:
    * more verbose comment for mpf_poll_status()
[https://lore.kernel.org/linux-fpga/20221229104604.2496-1-i.bornyakov@metrotek.ru/]
  v5:
    * revord "fpga: microchip-spi: move SPI I/O buffers out of stack"
      commit message "Use allocated buffers" -> "Use cacheline aligned
      buffers"
    * drop __aligned(ARCH_KMALLOC_MINALIGN) attribute of struct mpf_priv
      member "rx". tx and rx are used synchronously by dma, they could
      share a cacheline.

Patch #1 is good to me now. And applied this series to for-next

Thanks,
