Subject: [PATCH 4.19 442/639] ARM: dts: iwg20d-q7-common: Fix SDHI1 VccQ regularor

From: Fabrizio Castro <fabrizio.castro@...renesas.com>

[ Upstream commit d211650a87edc7f4130651c0ccbc0a4583fd72d3 ]

SDR50 isn't working anymore because the GPIO regulator
driver is using descriptors since
commit d6cd33ad7102 ("regulator: gpio: Convert to use descriptors")
which in turn causes the system to use the polarity of the
GPIOs (as specified in the DT) for selecting the states,
but the polarity specified in the DT is wrong.
This patch fixes the regulator DT definition, and that fixes
SDR50.
