Add a common device-tree include file with MMC/SD IOdelay data for DRA76x SoC based on the linux DTSI file.

In the most common case, IOdelay data available in datamanual can directly be used. This file caters to that common case.

Data is based on DRA76x datamanual, SPRS993A, revised July 2017.

Now that we have a device-tree include file with common MMC/SD IOdelay data for DRA76x SoC, shift the EVM device-tree file to using that. Also fix the name of the IO voltage regulator for mmc1.

Beside enabling the support for HS200 in mmc core, enabling the HS200 support in the SPL requires multi-dtb support in the SPL because pinctrl and IOdelays vary across SOCs.

Also we need to make sure that the pinctrl properties arenot removed from the dts by setting CONFIG_OF_SPL_REMOVE_PROPS to remove only clocks and interrupts properties.

The SPL can't use high speed MMC modes if the associated pinctrl and IOdelays are described in the DTS. Make them available in SPL by tagging the nodes with 'u-boot,dm-spl;'
