There is leakage on SYS_RST_ODL from the internal pullup cr50 has on
DIOM0. This change removes the internal pullup.
Without the internal pull up SYS_RST_ODL is not pulled up whenever the
EC is off. I changed how sys_rst_asserted is handled so it will ignore
the sys_rst interrupt whenever rbox asserts EC_RST to make sure cr50
doesn't reset itself every time it resets the EC. If the EC resets
itself and sys_rst_l is no longer pulled up, it is fine if cr50 resets.
BUG=chrome-os-partner:53544
BRANCH=none
TEST=manual
'rw 0x40550010 1' causes the EC to reset but not cr50
On the development board verify DIOM0 is not pulled up.
Test cr50 boots normally on reef and gru
