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.
