Primarily gpio device driver changes with some minor side effects
under arch/arm and arch/x86. Also includes a few core changes such as
explicitly supporting (electrical) open source and open drain outputs
and some help for parsing gpio devicetree properties.

"Primarily gpio device driver changes with some minor side effects

Fix up context conflict due to Laxman Dewangan adding sleep control for
the tps65910 driver separately for gpio's and regulators.

The present _get_value routine returns the contents of the GPIO Monitor Pin
Status Register(GPMR) starting from the bit whose value is requested to BIT 0
(irrelevant bits are replace by 0).
For e.g. if we request the value of GPIO 6 in the earlier implementation the
value returned is:
BIT6 followed by 6 0's
whereas it should just return BIT6.
This patch addresses the same.

Adds support for boards which have an STMPE GPIO device without the
interrupt pin connected. This means that no interrupt can be received
but the GPIO pins can still be driven and read.

STMPE801 is a GPIO expander. GPIO registers for 801 are slightly different from other
variants. This patch adds support for STMPE801 in stmpe gpio driver.
