Add sam_linux_is_optee_available() which allows to know if OP-TEE is

ARM: at91: add code to handle secure calls2022-05-12T11:50:20ZClément Légerclement.leger@bootlin.com2022-05-02T15:22:18Zurn:sha1:0c9fd821175a5634e00aa391f5f202f8ed4c9223
Since OP-TEE now has a more complete support for sama5d2, add necessary
code to perform SMC calls. The detection of OP-TEE is based on a
specific device-tree node path (/firmware/optee) such has done by some
other SoC. A check is added to avoid doing SMC calls without having
OP-TEE.
