spi: mpc512x-psc: Convert to use GPIO descriptors

Browse source

This driver is already relying on the core to provide
valid GPIO numbers in spi->cs_gpio through
of_spi_get_gpio_numbers(), so we can switch to letting
the core use GPIO descriptors instead.

The driver was assigning a local function to the custom
chipselect callback, but I chose to just open code the
gpiod setting instead, this is easier to read.

The only platform that overrides the cs_control callback
is the mpc832x_rdb.
