h1r9: workaround platform detection problem

Browse Source 
On the first spin of r9 one of the pins used for platform detection is
pulled up to VAA, not VCC, and VAA hasn't been switched on yet at the
time of platform detection. This results in r9 being misidentified as OG
from time to time.

As a temporary workaround until the next board spin, change the platform
from OG to r9 if it is detected as OG but has r9 pin straps.
