[U-Boot] [PATCH 0/7] Handle GPIO_ACTIVE_LOW in gpio-uclass

As Peng pointed out in [1], GPIO_ACTIVE_LOW is currently being
parsed by driver-specific xlate routines, and an NXP/mxc-specific
patch ([2]) to do the same on those processors is pending.

Upon further inspection, I found that many arch-specific xlate
routines were present only to parse either or both offset and
the GPIO_ACTIVE_LOW flag, both of which can be handled at a global
level.

This series adds global support for GPIO_ACTIVE_LOW and removes
the architecture-specific gpio xlate routine from five drivers.

It also removes the handling of flags in the tegra gpio driver,
though a custom xlate is still needed.
