soc/amd/common/psp_smi_flash: refactor SPI controller busy check

Since the functions that call 'spi_controller_available' end up checking
if the SPI controller is busy, refactor the function into
'spi_controller_busy' to simplify the logic on the caller's side. Also
move printing of the notice that the SPI controller is busy to
'spi_controller_busy' to not have that duplicated in caller.
