amd/stoneyridge/spi: Fix reads greater than 5 bytes

This corrects a bug in 918c8717 "amd/stoneyridge: Add SPI controller
driver".  Pass a pointer to din to the do_command() function so the
caller's copy is correctly updated.  The bug allowed reads <= 5 bytes
to work correctly (3 bytes consumed in the FIFO by the address) but
overwrote data in the din buffer on larger transfers.
