There is leakage on SYS_RST_ODL from the internal pullup cr50 has on DIOM0. This change removes the internal pullup on reef. On Kevin there is a bug preventing the EC from being able to pull sys_rst_l up high enoug for cr50 to detect that it is pulled high. This change adds an internal pullup back when cr50 detects that it is on a kevin or gru. BUG=chrome-os-partner:56945 BUG=chrome-os-partner:53544 BRANCH=none TEST=On gru and kevin remove servo verify when apreset is run on the EC it resets cr50 and the AP. Run pinmux and check that there is a pullup on diom0 on kevin but not on gru.
