mb/google/guybrush: rename baseboard GPIO table getter for clarity

Rename variant_pcie_gpio_table() to baseboard_pcie_gpio_table(), since
the GPIO table comes from the baseboard and is overridden by a separate
table from the variant.

Drop the __weak qualifier as this function is not overridden.

This is similar to the change made for skyrim in CB:67809
