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.
