spi: spl022: switch to use default spi_transfer_one_message()
Except for polling mode, this driver's transfer_one_message() makes use
of interrupt handler and tasklet. This is problematic because
spi_transfer_delay_exec(), who may sleep, is called in interrupt handler
and tasklet. This causes the following warning:
BUG: sleeping function called from invalid context at drivers/spi/spi.c:1428
Switch to use the default spi_transfer_one_message() instead, which
calls spi_transfer_delay_exec() appropriately.
