soc/amd/common: move GPIO register state save struct to gpio_banks.h

The common_i2c_save struct isn't specific to the I2C code and since it
contains the state of the GPIO control & status register and the state
of the GPIO MUX register, move it to include/amdblocks/gpio_banks.h and
rename it to soc_amd_gpio_register_save.
