Scott 9cd10a5a47 Cr50: Removed Reef EVT workarounds ...

- changed the pad assignment for plt_rst_l from DIOA13 to DIOM3;
- removed the board property used to keep uart rx disabled, Uart0 is
  now enabled by default on Cr50.
- removed resetting fallback counter on USB updates for reef boards,
  they are going to use the same mechanism as kevin and gru.

BRANCH=none
BUG=chrome-os-partner:56540
TEST=Tested on Reef Board ID 1 and Gru Board ID 1. Verfied that
     plt_rst_l signal is being detected and that there are no
     interrupt storms related to not having a pullup resistor on the
     uart rx line. Verified that both platforms successfully boot into
     chrome OS using cr50 TPM.
