[PATCH 0/2] ke-am62x-sk_evm: add ospi support

[Dhruva Gole]

There's a S28HS512T Flash (by Cypress) on the AM625 SK EVM.
- Add necessary DT nodes to enable OSPI interface with this flash.
- Enable all configs that enable the OSPI related drivers and commands
  like SF probe.

Tested on my AM62 SK EVM, attaching logs below.
