spi: sh-msiof: Convert to use GPIO descriptors
Convert GPIO chip selects in the Renesas MSIOF SPI driver from legacy
GPIO numbers to GPIO descriptors.
Notes:
- The board file for the SH7724-based Ecovec24 development board now
registers a GPIO descriptor lookup, instead of passing a GPIO number
through controller_data,
- sh_msiof_get_cs_gpios() must release all GPIOs, else
spi_get_gpio_descs() cannot claim them during SPI controller
registration.
