This switches the ST SSC SPI controller to use GPIO
descriptors from the core instead of GPIO numbers.
It is already using the core parsing of GPIO numbers
so the switch is pretty straight-forward.

If the calls to devm_platform_ioremap_resource(), irq_of_parse_and_map()
or devm_request_irq() fail on probe of the ST SSC4 SPI driver, the
runtime PM disable depth is incremented even though it was not
decremented before. Fix it.

The driver forgets to call pm_runtime_disable in probe failure
and remove.
Add the missed calls to fix it.

Use devm_platform_ioremap_resource() to simplify the code a bit.
This is detected by coccinelle.

devm_* API is supposed to be used only in probe function call.
The resource is allocated at 'probe' and free automatically at 'remove'.
Usage of devm_* functions outside probe sometimes leads to resource leak.
Thus avoid using devm_* APIs in .setup/.cleanup callbacks.

Due to the newly upstreamed 'critical clocks' API we can now
safely handle clocking in the SPI and I2C drivers without fear
of catastrophically crippling the running platform.

spi_setup() will test unsupported mode bits before calling spi->master->setup.
Thus remove duplicate code to test unsupported mode bits in spi_st_setup().
