Import sdma-imx7d.bin from linux-firmware repository at commit:
55edf5202154: ("imx: sdma: update firmware to v3.5/v4.5")
Cortex-A7 boards (i.MX 7 based) use different SDMA firmware than i.MX 6
boards - bundle the correct files in per-subtarget kernel options.

This is first step in migrating to a generic i.MX target which in the
next steps will also get divided into arch-specific subtargets.
In the result, this will make it possible to support, within a single
target, also other modern NXP i.MX families, like the i.MX 7, i.MX 8
or recently introduced i.MX 9.
