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@xxxxxxxxxxx/] v2: * split into 3 distinct patches [https://lore.kernel.org/linux-fpga/20221226142326.8111-1-i.bornyakov@xxxxxxxxxxx/] v3: * fix polling stop condition in mpf_poll_status() as Ilpo suggested.
