gpio: fix up SPI submenu
- Relax dependencies on SPI_MASTER for drivers in the SPI menu that already has this dependency. - Move out the expander that would be hidden for I2C access if SPI_MASTER was not selected. Tentatively create a separate menu for this. - Move the ZX SoC driver to memory-mapped drivers, this must be a mistake and only worked because the system has an SPI master enabled at the same time. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
