Rename GPIO_HI_Z macros to more descriptive GPIO_ODR_HIGH/LOW
GPIO_HI_Z was a bit misleading (it's high impedance by default, but it's
actually an output not an input), but when we added GPIO_HI_Z_OPEN to mean
"open-drain output, pulled low by default", it got too confusing.
This renames those macros to:
#define GPIO_ODR_HIGH (GPIO_OUTPUT | GPIO_OPEN_DRAIN | GPIO_HIGH)
#define GPIO_ODR_LOW (GPIO_OUTPUT | GPIO_OPEN_DRAIN | GPIO_LOW)
BUG=chrome-os-partner:18788
BRANCH=none
TEST=none
No functional change, just renaming some macros. If it compiles, it should
be unchanged in behavior.
