[PATCH 0/2 v2] spi: s3c64xx: use "cs-gpios" in spi node instead of "cs-gpio"

[Naveen Krishna Chatradhi <ch.naveen@samsung.com>]

Currently, spi-s3c64xx.c needs "cs-gpio" chip select GPIO to be
defined under "controller-data" node under each slave node.

&spi_x {
        cs-gpios <>;
        ...
        slave_node {

                controller-data {
                        cs-gpio = <>;
                        ...
                };
                ...
        };
        ...
};

Where as, SPI core and many other drivers uses "cs-gpios" for
from device tree node.

Hence, make changes in spi-s3c64xx.c driver to make use of
"cs-gpios" from SPI node(parent) instead of "cs-gpio" defined in
slaves "controller-data"(child) node.

Also, fixes a compilation warning and corrects the DTS nodes for
Exynos4210 based SMDKv310, Exynos4412 based Trats2, Exynos5250 based
SMDK5250 boards.
