This reverts commit 214c719eed.
CB:45857 overrides the GPIO PM configuration if Cr50 does not support
long interrupt pulse width. More recent Cr50 Firmware versions support
long pulse width and hence the GPIO PM can take the default

No recent Chromebooks have used I2C for TPM communication, and as a
result, a bug has crept in. The ability to extract Cr50 firmware string
is only supported via SPI, yet code in mainboard and vendorcode attempt
to do so unconditionally.
This CL makes it such that the code also compiles for future designs
using I2C. (Whether we want to enhance the I2C protocol to be able to
provide the version string, and then implement the support is a separate
question.)
