mb/google/octopus: Update GPIO_178 in early_gpio_table in baseboard
This change updates the configuration of GPIO_178 to be active low as
per latest revision on different octopus variants. This effectively:
1. Gets rid of early_gpio_table in different variants -- phaser, meep,
fleex, bobba.
2. Deprecates board id < 2 for bobba, board id < 1 for fleex and
phaser.
3. Adds special early_gpio_table in yorp which has GPIO_178 as an
active high signal.
