Provide a generic pad.tcl script to create a padfram for the IHP SG13G2 platform. The design specific config.mk has to define all pins for the north, south, east and west bank.

Additionally, switch the I2C GPIO Expander to this script.

This padframe will the 70x70 bondpad by default, but can use
another bondpad via IO_BONDPAD_NAME and IO_BONDPAD_SIZE.

Use the platform specific pad.tcl file and only provide all pins
for each bank.
