2019-03-27mb/google/octopus/variants: Remove bipEvan Green
Remove bip, as it is no longer actively developed, and its EC overflowed storage, so the EC build is no longer viable.

2018-09-06mb/google/octopus: Configure H1 interrupt pad using Rx level configFurquan Shaikh
This change configures GPIO_63 (which is used for H1 interrupts) as Rx Level. This ensures that the signal gets passed on to the next logic state as is and the APIC entry can be configured to trigger interrupt on level or edge as per the kernel driver expectation. TEST=Verified that no H1 interrupt timeouts are seen with 100 iterations of warm and 100 iterations of cold reboot.

These pins should not have pull downs configured in standby state as that can cause contention on the termination circuitry and lead to incorrect behavior as per Doc# 572688 Gemini Lake Processor GPIOTermination Configuration. Furthermore, some of these pins were configured with normal termination of None which would as per above mentioned document lead to a standby termination of None anyways.
