Add the standard cells as submodules.
...
They are being added as submodules from the
https://foss-eda-tools.googlesource.com/ repository due to their large
size. People are encouraged to only initialize and clone the submodules
needed for their designs.

Limited release of the SKY130 IO and periphery cells.
...
Release of a subset of the full IO. This release includes;
* Power pads;
- High voltage - `top_power_hvc_wpad`, `top_ground_hvc_wpad`
- Low voltage - `top_power_lvc_wpad`, `top_ground_lvc_wpad`
* Reference generators - `top_refgen`, `top_refgen_new`.
* Standard GPIO (`top_gpiov2`).
* I2C compatible GPIO with over-voltage tolerance (`top_gpio_ovtv2`).
* Special SIO (`top_sio`) with differential macro (`top_sio_macro`).
* System wide reset influencing XRES cell (`top_xres4v2`).
Future release will include;
* Original standard GPIO (`top_gpio`).
* More power pad versions.
* More XRES cells.
* More reference generators (`top_vrefcapv2`, etc).
* Spice and CDL models for the IOs.
