tee: optee: sync cache on pre-reloc OP-TEE invocation

This change ensures both U-Boot and OP-TEE see the same content
from shared memory when OP-TEE is invoked prior U-Boot relocation.

This change is required since U-Boot may execute with data cache off
while OP-TEE always enables cache on memory shared with U-Boot.
