boards: ti: skam62evm: Added west build target for ARM Cortex A53 for the SK-Am62 EVM

[Kronosblaster]

Provided for a direct method to build for the TI SK-AM62 (sk_am62). It was tested to be functional on the AM62B-SKEVM-P1 rev A board. Simple testing can be done by building the hello world example with:
west build -p -b sk_am62/am6234/a53 samples/hello_world.

Some minor issues. Your history is still a little bit off. Just remove this "Fixed documentation errors" and squash those changes into one commit.

For example:

get reset --soft 35caaa199aba3b97614eb3161e23b354411d8af8
git commit --am

@Kronosblaster can you please rebase to main?

[kartben]

MUCH better, thank you! Doc is almost good to go, just one last comment.
