dt: name all Tegra binding docs consistently
Rename all Tegra binding documentation according to the first or primary compatible value they describe. This provides a clear naming scheme for the files, and prevents any naming conflicts should future SoC versions require their own binding. Signed-off-by: Stephen Warren <swarren@nvidia.com>

1* NVIDIA Tegra Secure Digital Host Controller
2
3This controller on Tegra family SoCs provides an interface for MMC, SD,
4and SDIO types of memory cards.
5
6Required properties:
7- compatible : Should be "nvidia,<chip>-sdhci"
8- reg : Should contain SD/MMC registers location and length
9- interrupts : Should contain SD/MMC interrupt
10- bus-width : Number of data lines, can be <1>, <4>, or <8>
11
12Optional properties:
13- cd-gpios : Specify GPIOs for card detection
14- wp-gpios : Specify GPIOs for write protection
15- power-gpios : Specify GPIOs for power control
16
17Example:
18
19sdhci@c8000200 {
20 compatible = "nvidia,tegra20-sdhci";
21 reg = <0xc8000200 0x200>;
22 interrupts = <47>;
23 cd-gpios = <&gpio 69 0>; /* gpio PI5 */
24 wp-gpios = <&gpio 57 0>; /* gpio PH1 */
25 power-gpios = <&gpio 155 0>; /* gpio PT3 */
26 bus-width = <8>;
27};
