Cr50: Add gpio input for platform reset (plt_rst_l)
For TPM operation with Intel chipset APs, the signal PLT_RST_L needs
to trigger a TPM reset. For current Reef boards, this signal is
connected to DIOA13. The next version will have it on DIOM3.
This CL adds support for platform reset connected on DIOA13 and uses a
new board property so that it doesn't affect Kevin/Gru.
BRANCH=none
BUG=chrome-os-partner:55115
TEST=manual
Used H1 dev board configured as Reef. Created high to low transisition
on to verify that platform reset was detected. Tested on Kevin to
ensure that resets were not occurring.
