spi: Allow to have all native CSs in use along with GPIOs
The commit 7d93aecdb58d ("spi: Add generic support for unused native cs
with cs-gpios") excludes the valid case for the controllers that doesn't
need to switch native CS in order to perform the transfer, i.e. when
0 native
... ...
<n> - 1 native
<n> GPIO
<n> + 1 GPIO
... ...
where <n> defines maximum of native CSs supported by the controller.
To allow this, bail out from spi_get_gpio_descs() conditionally for
the controllers which explicitly marked with SPI_MASTER_GPIO_SS.
