fdt: Add a function to get the alias sequence of a node
Aliases are used to provide U-Boot's numbering of devices, such as: aliases { spi0 = "/spi@12330000"; } spi@12330000 { ... } This tells us that the SPI controller at 12330000 is considered to be the first SPI controller (SPI 0). So we have a numbering for the SPI node. Add a function that returns the numbering for a node assume that it exists in the list of aliases. Signed-off-by: Simon Glass <sjg@chromium.org>
